Hi,
Just bought a Hydra Stream 1. Just 1 question on install - Is the device directional? Meaning how do you tell which is the inlet and outlet, or is it not important? Thanks. |
Quote:
Hydra stream is not directional and you may treat either way as inlet or outlet for your preference setup. |
Hi, I had installed Hydra 20 a week ago for my 60 litre goldfish tank and I find significant reduce in Nitrate. But, I see continuing rising of the amonia level at >8mg/l
So, can u pls advise what could be went wrong? |
hmm... just wondering is this thing reliable or no as i am eager to try one?
seem like there is a few negative feedback on this. Those with negative feedback, the QH doesnt reply to their post. |
no device is perfect. just like if you are lucky u get a ak brand dvd player it can use up to 10 yrs also wont spoilt, but if u are suay u get a so brand it can actually spoilt the monment u use it.

Thanks for your interest in getting hydra stream for your tank setup. You may want to contact our retail on how to go about on your purchase as i understand that you are not in Singapore. Thanks. As for the reliability, so far we acknowledge that we do have some pump which the impeller might have broken down but that is very minor qty. As much as we will want to have a perfect products, but we can only try to minimise the defect and not totally eliminate it. Thanks for the understanding. |

The cata pure which hydra is using is releasing strong reactive Hydroxyl (OH) ions, which is the key to the cleansing reactions. It constantly pushes the ionization of toxic Ammonia NH3 into non-toxic Ammonium NH4+, thus greatly preventing fish kill due to toxic Ammonia Most Ammonia Test Kits in the market measures Total Ammonia Nitrogen (TAN). They measure the total sum of toxic Ammonia (NH3) and non-toxic Ammonium(NH4+) in the water. Hydro Pure Technology constantly pushes the ionization of toxic Ammonia NH3 into non-toxic Ammonium NH4+, thus greatly preventing fish kill due to toxic Ammonia. Therefore, it is normal that these test kit results in high readings as they measure total sum of toxic Ammonia (NH3) and non-toxic Ammonium (NH4+). |

Thanks for the feed back. Will be getting the stream 2. Really appreciate for the fast reply. |
Sorry a noob question:
Does the hydra lowers nitrate ? My ammonia n nitrite are 0 n my concern is the high nitrate . |

It also helps to keep Nitrites NO2 and Nitrates NO3 to minimum levels at all times |

Hi Qian Hu, I'm interested in your product and would like to find out more ..... I'm a little confused per your response above. If the Ammonia test kits measures TAN, and Hydro Pure Technology pushes toxic Ammonia NH3 into non-toxic Ammonium NH4+.... shouldn't the TAN after using the Hydro filter remain the same (or even lesser) vs the TAN before using the Hydro filter? The difference should be lesser toxic ammonia and more non-toxic ammonia after using the filter? TAN stays constant unless BB further breaks it down to nitrites.... then the TAN should drop. In the situation mentioned by 50cents.... it appears TAN went up .... is this expected? Or maybe this is a new tank and ammonia is spiking? Thanks |
Hi,
Thank you for your question. I believe many people have similar questions and doubts. We will answer as below. There are many kinds of aquarium set up and they can have many differences, in tank size, number of fishes, types of fishes, size of fishes, types and size of filtrations, planted tanks, marine tanks…etc. Perhaps let us explain the Working Principles of Hydra in layman terms so that everyone can understand better, when they apply it to their own aquarium setup. Hydra basically functions as a Detoxing Depurator for aquariums. Hydra detoxifies harmful toxic Ammonia NH3 to non-toxic Ammonium NH4+. Hydra also oxidizes toxic nitrites to non-toxic Nitrate. Hydra’s continuous reaction eventually yields Nitrogen N and Water, so it depurates the water. Firstly, let us understand the nitrogen cycle: Fish waste and leftover feeds -> Ammonia(Toxic)/Ammonium(Non-toxic) -> Nitrite(toxic)-> Nitrate(non-toxic)-> Nitrogen When Hydra is switched on, yes, Total Ammonia Nitrogen (TAN) will rise initially. The reason is, the Ammonia is being pushed to become Ammonium. The Total Ammonia Nitrogen (TAN) will rise, because fresh ammonia is still being produced by the fish waste and feeding. Yes, Nitrite will drop because it is being oxidized to Nitrate by Hydra. Nitrate will rise slightly and stabilize eventually. This is fine because nitrate is non-toxic. In general, Hydra works as a detoxifier and depurator for your aquarium. |

Hi, I enjoying my Hydra cos it keeps things simple for me. I know that the cartridges is only for change once a year. However, I am thinking of replacing after every 9 months since it is switched on 24/7 for me. You haven't tell me where I can buy.... I stay in Seng Kang so I won't be able to head to your office. Hehe. |

Hi, The new Hydra cartridge is not launch yet in the market and will most likely will only be available in most LFS end of this year. |
Hydra Stream 2
Finally got myself one OF Hydra Stream 2.
Sharing on the stream 2 photo and installation manual. I believe other people also wondering how the system look like. Until I hold one today specially bought by a Singaporean friend and send over to me. Really thankful for his kindness for driving all the way to YI HU at Jalan Lekar and delivered to orchard hotel. http://i102.photobucket.com/albums/m...26/stream2.jpg http://i102.photobucket.com/albums/m...ualstream2.jpg I wish for those who like to buy one of this can know how is the setup look like. |
Hydra 20
I have been using the Hydra20 for a few months now for my simple 2ft tank. There is no other filtration in it. I am just a typical average fish hobbyist that play with simple bare minimum setup. All my life I have tried many internal filters before and also sponge filters, overhead filters, hand on filters etc... This Hydra filter is quite amazing. Every week I change 10% of water. Haven't even open the hydra to wash before. Somehow the water always just remains clear and no smell at all. 50 over assorted small fishes and shrimps are healthy. I must say, all my Iife, I have never seen an internal filter work so well before.

Hydra20 only got 1 cartridge but good enough for my simple tank with small fishes. hydra 20 flow is just right for 2ft tank. Hydra30 flow will be too strong for the fishes.

Hi bro, I did not fix the air tube, and I place below the water surface, so I didn't have any air bubbles. If u did not use the tubing, and u put the top of the hydra at the water surface, it may draw bubbles. Else u can adjust the flow rate slower to reduce the bubbles being drawn.
|
Bro, how to adjust the flowrate?

if u r a itchy-backside person like me whom always buy fishes whenever u liked resulting in overstocking.. hydra is a a good complimentary product.. my main tank 5x2.5x2.5 was running with a 4 ft sump and 2x hydra 50 with over 20 fishes with 2 5 inch ray... all eating and water crystal clear... :)

My tank is 200 liter tank, is it okay to use hydra 50 instead of 40? Will it still be effective? I may upgrade the tank in about 1-2 yrs time

Hi QH,
Is hydra 30 for 2.5ft x 1.5ft x 1ft tank sufficient? Do I need to add other external filtration? Keeping only single aro about 6inch. When I move to 5ft tank. Can the hydra 30 sufficient to support also? Please reply. |
