Seriously you should not be covering up the whole pond with board without any holes. You should be using perforated board or board drilled with holes. The logic behind is when doing this the heat cannot escape under the hot sun light to the extend that your fish might be cooked. In science high temp water would loss heat through evaporation, by covering up the water will condense back and heat go back to the water. This is like a 'green house' effect or a heated tea pot with closed lid. No surprise you seeing condensation. Fortunately your fish still alive (I supposed your white background helps, if black gone case liao). I suggest the immediate action is to remove the board and replace with something with holes.
With regards to the nitrate is because the algae has been removed intentionally. Nitrate and algae growth goes hand in hand, striking a balance and checking one another. Removing the algae caused imbalanced and the nitrate to shoot up. Using the plant idea is good, like pandan or money plants. You can also consider getting those potted water plant (if you don't mind the soil). The only disadvantage of having plants is that the old leaf and roots will decay and rot, further causing ammonia and contamination issue and might even choke you filtration. Do remember to protect your pump by enclose it within a basket, as any of the leaves get in there will damage the pump. |
Bro LauLanChu, really thanks for advises... Cannot imagine that I nearly kill all my fish by covering in this way 😓 also dont know why I forgot about all these science theory, maybe I am getting old 😅 I guess I have to remove the board and use back the netting (probably put double or triple layers) until I have a very good solution to this. Perforated board will obstruct the viewing from top?
Thanks those bros who know me and whatsapp me for the solutions... I appreciate very much. I am looking for more options where the covering will looks nice... Cheers. |
I guess the thick glass or temperature glass with window frame....
Is a better option. Risk if some one thro things down will shatter. Can do like car bonnet actuation.... So can open or slant the glass Regards to the heat.....when install leave a 1 inch gap higher so all rOund got Vent Lor....or as maker to make holes |

maybe can try something like this?
instead of net, use acrylic or glass panel? http://i284.photobucket.com/albums/l...4072010157.jpg |
Hi Thomas, I have to say you have a very nice FGT setup.
However, you have to constantly overcome new challenges by means of experimenting new measures only to find out that it may solve one problem but creates other issues. I read this entire thread from the very beginning to the latest post before I went to bed last night. Honestly, I feel your joy and pain! :) Now, if I may offer you a more practical approach to attempt to resolve these challenges, please consult a reputable landscaping contractor who has more experience in handling and maintaining ponds for condos and alike. It does no harm to listen or consider their suggestions before you make your next move. You do have a very tricky situation given the surroundings, restrictions and limitations. We would be very interested to find out what clever solutions these professionals have to offer. Please consider this and keep us posted. Best of luck! |
Hi Thomas, I borrow this pic from the goldfish folder. you may want to consider this type of cover for your tank. maybe use smaller holes opening for the netting.

yaa...pVC-surround..... or window frame style....
if u wana keep those acrylic sheets.... then consider drilling holes on them ;) what kind of upstair neighbours u have...? all OK so far? no free-gifts from them? |
I thought use pail to cover head.. :P

Seriously..... the money you spend on the acrylic board, top up abit can make a high fence primeter to surrond the pond. Solve the problem once and for all. |
Indeed, there are lots of challenges fot outdoor pond. Better get advice from the expert causeypu already experienced a lot of ups and downs.
Stay in there and don't give up. Its really a very beautiful outdoor setup which I can only dream of. |
Thanks for all the concerns, advises and most importantly, the heartfelt encouragement... It touches me😊 The 'helmet' proposal has made my day too 😆 thanks bro Heuer for the pic of the cover...
Having an outdoor fgt is challenging as there are more 'problems' to handle than an indoor tank. This is my first outdoor fgt and thus I would like to share my good and bad experiences so that bros who have come across similar situations, will know what are the do and donts. I hope in a way it helps... Actually I was advised by some builders to fence the pond. This is one of the easier way but there will be ugly supports required to make the fence firm and safe at the front glass area. I did not take this approach as I myself do not really like this fence idea. It makes me feel 'separated' from my fish and it is not as presentable as a whole. (but I will still like to thank bro Fireblade for suggesting and taking the effort to post a pic for me to understand better 😊) There are also other suggestions but it either has ugly supports to hold the structure or adds heavy weights directly onto the fgt. I feel uncomfortable both ways... This is why I choose the netting cover method as I feel 'closer' when I can view the fish directly above the water. I had just bought a very much thicker netting this time and I am quite sure that it will not break easily. Have a comparison here. http://i1371.photobucket.com/albums/...psm90iqgpj.jpg I will also try to do something at the sides of the fgt so that the fish will not have chance to jump and 'slip' through the sides anymore. I hope this will solve my problem😊 Solving the problems when they arise, and making the fgt a better and nicer home for my fish is part and parcel to me. It makes my fish keeping hobby interesting with lots of excitement when it turns out nice and of course, there will be disappointment at times when it fails. However, as long as the enjoyment outweighs the sadness, I am happy with it. I hope u have enjoyed as much as I do. Happy fish keeping. Cheers Below is a pic of the new green netting. http://i1371.photobucket.com/albums/...psgobddoyw.jpg |
Agree, that is the fun of it, 'building your own pond'. We can do away with a pond specialist, but that kills the hobby.
I also have the same problem as you, fish jumping. I still got no idea how to prevent fish from jumping, except to cover it up. When you have jumpy plus ferocious fish sure they will jump when harrassed or chased. Your netting is good, except you have to keep watch when you have smaller jumpy fish. They will get trap in between netting. One way to avoid is not to keep those. Also I could have missed something, your pond looks to me like closed up near with wall or partition. The concern of fish jumping should be minimum as they would eventually drop back to the pond? |
Wat are u gonna do with those Plexiglas aka acrylic sheet?
|
I am thinking of DIY the acrylic board into a plant holder to be put at the back of the pond, so that I can put in more plants. Any idea beside Pandan, what other type of plants can be submerged direct in water to grow? Any help on this?
The water looks clear now 😊 https://m.youtube.com/watch?v=a3iRsDW1EiY |
money plants? fast growing and abundant. faster growing plants absorb nitrates faster too.

Aquaponics, u'll be spoil for choices, but @ this stage will need plenty of mod. go google to conceptualize idea. |
TS, are those round balls on your window side Solar LED lights? If they are, when they light up at night, the light will attract insects and that probaly explains why your are has been jumpy at night...
A rigid netting is advisable cos if any fishes where to jump right into one of the opening in the net, they will not get stuck and caught hanging in mid air... Last but not least, it is a very impressive fgt pond!! |
I can see there're torn tails and fins among other fishes beside of the aros, these're are sign of bb's/bacteria's saturation, fighting goes beyond worn out tail and fin ...Btw, did u add any bbs to enhance the nitrogen cycle? Bacts/free floating bbs are more active during sundown they're probably chewing on the fishes. these will stress and make fishes aggrasive some may be jumpy to get out of the situation. Sometime due to higher flow rate, to suppress green water may be possible but insufficient time to zap the free float bacteria, u either need to reduce flow rate to match UVc lamp spect. or increase UVc lamp power (watts) to over come the short fall. I'm not insisting, only saying this cud be one of the possibility nia nia.

Somehow the netting still looks risky for the fish.
I spotted 1/2" SS wire mesh at the hardware store the other day along with alu. square tubing, it will be quite easy to make a cover with the mesh and tubing. Do consider that. |

I'm using the 2inch SS wire mesh as a pond divider. However, sad to say this, SS is no longer pure:mad:....then can see rust stain!:( |
what abt use PVC pipe to form a rectangular frame. Then use the netting to stretch and tight firmly to the end of the PVC pipe frame. will looks neater than sagging netting.
|
Bro care to share where u buy the netting?
|
Yes bro, I am enjoying the fun of building it... As for the jumping out, the main worry is the front and the stairs and filter areas. But as I am using the net cover, there is no concern. I guess this current netting is really rigid enough as is totally different from the previous net. We shall see how it goes... Thanks bros for the reminding....
Thanks Dennis, aquaponics is a good idea 😊 I will look into this. Yes, those round balls are solar lightings emitting very dim lights. I dont see insects around these lightings. I am more worry about the UV lighting at the back of the filter chamber. It is much brighter than these light balls. However it is not very much covered by the pandan plants... But still can see.... Should I use something like a big sponge to place above the UV light? Mentioning about this UV, I just wonder if the pandan plants that submerged in this chamber together with the UV, is the pandan having a higher chance to rot, instead of growing? Just wondering if the uv will have impact to the pandan. Another question is that I have placed air stone in each filter chamber, will this hinder the growth of pandan as well? Should I remove the air stones and pit them into the main fgt? Any advises? Yes bro Nutx, some SS will still rust... I have no intention to try it at the moment. Honestly if this current net (which I think is very rigid already) still fails me, I will try the netting that bro Heuer had shown previously (Not the tub to protect my head 😅 lol ) I do not like the pvc frame and will avoid the frame if possible... Lets see how things go... Ok, I bought the netting in those old shop house along beach road. There are 2 shops having similar name but one with a 新 infront of it... I go to the one without 新 infront as there are some netting being displayed outside the shop. I forgot to take the namecard so cannot tell exactly the address. PM me if you need further description of the shop... For the mesh products, you can go to blk30 Kelantan Rd #01-91 www.meshlxf.com.sg This one the shop pass me the namecard 😊 Lastly I am happy that I bought few plants from the nursery yesterday. The Chinese attendant told me that these plants can grow directly with water... I just bought and tried lo... Hopefully they will grow... Cheers |
UVC exposure to fish will kill the fish, to plant I am not sure but might be risky. Airstone should be fine.
When you have plants is a good sight but also have it negatives. One is the dropped leafs and rotton rots as mentioned, another is the insects like spiders, bugs, flies that may infest (if you don't use insecticide prevention, you know what I mean as this will cause harm to fish). So I would say have plants moderately. As for the jumping since you only have 2 sides to take care of, why don't you think of trying to raise up the level of that 2 sides to the height that will keep the fish from going out? That will get rid of all the covering issue and you have a good sight and full view of all the nice fishes. |
Thanks bro...
For bros that are thinking of putting the plants exposing to the UV light, please do NOT do so. The plants will die. All my pandan plants in the same chamber of UV light (the last chamber), are all gone cases and I have to remove all the rotting plants 😓 This is another learning experience for me 😊 Wondering how high will an aro normally jump? If there is a 1ft acrylic wall, will it be sufficient? Any advise? |

Wahaha.... 2m? I think I can forget about this then 😅 thanks for the video....
So far this netting is really strong, should be no problem at the moment.... 😊 |
Today I decided to clean up the 1st and 2nd of my sump compartments. To my horror, I discovered some white stuff and something like eggs on the lava rocks, the nettings and some even on the brushes. Below are 2 pics.
I spent few hours cleaning these away... I am not sure if the remaining compartments are infected with these or not, I will clean them in 2 weeks time. Hopefully bros here could advise on what are they? Are they the midges eggs or my goldfish feeder eggs? TIA. http://i1371.photobucket.com/albums/...psbmbmblw1.jpg http://i1371.photobucket.com/albums/...psbil1jmnv.jpg |
can you show a picture of your sump tank?
would like to know whether your water pump is submerged in water or outside. Because i have an outdoor pond as well, but the problem i face is that my water turns really really HOT. im not sure whether is it the afternoon sun or is it because of my water pump (runs very hot as well). I have since relocated all my kois and removed all the water. thinking of the next step to do. |

if that is the case,do no harm,your rays will love them(if you hv ray) in a tank or pond,if you hv just a ray,you notice the filter or sump compartment hv thousands of water snail thriving,but you cannot find them in the tank,because those are delicious food for rays:) |
Bro Relax, thanks for the ID. At least I know what are they 😊
Are they some FOC items that I had got unknowingly from you? Lol... Bro Jyn1989, my water feels warm occasionally too... even though at this period of the year, there is totally no Sun at my pond area... I do not know what is causing the water to feel slightly warm, not hot. The pumps are submerged in the last compartment. Is not easy for me to go over there as I had plants along the chambers now... |
Thank you for posting up your pond build. this is a beautiful setup. please continue to blog this and keep us updated.
|
bro....water temperature will follow the air temperature even if there is no direct sun light.
pump definitely will increase the temperature, so depend on vol of pond. maybe 1 degree diff? concrete get heat up by sun will transfer heat into the pond too! I used to have a pond on average 30-33 degree, even at night....:( |
Bro Nuts, thanks for the advises. It helps 😊
How is your pond? Any midges problem so far? I do not know why out of sudden, my midges problems are gone... Have been doing many things to try to solve it and it doesn't seem to work at all... Then suddenly it is gone!!! What a relieve for me 😊 |
