Unable to groom the tank after 4 years

bro,

I have my marine tank setup in Dec 2004. Since day1, I am not able to keep fishes like Tang, Coral and anemone for more than 3 months. Some die a day or less than a week. My tank is always grown with hairy, brown and red algae. I am very dis-hearten after many years of attempts. I suspect is my setup or maintenance not correct. This year, I started to change partial water regularly, but not very great improvement. Would like to seek for expert advise and help here. Thanks. I just tested my water last night, and this is the parameter.

N02 = 0.2
PH = 7.6
KH = 10

My tank is 3' x 1.8' x 1.8'
Filter = Canister
T5 lighting.


Regards,
Bobie

hmmm that bad bad. . .

i am very new to marine but manage to keep my fish and anemone well.

but how come ur PH = 7.6 . . . i think should be 8.3 like that leh . . . i think u go to some shop see they have those power that keep hp to that level.
and my temperature is at 26 to 27

What to do... am still struggling ... Does Alkaline buffer help?
My temp is about 28. What are the testers you use?

Imo a bit low ur salinity. Anyway for the algae problem, do u over feed? What water do u use for WC? Hearsay tap water contribute to algae problem. I nv use tap water before for WC hence dunno how true it is. As for the dead coral, anemone, is it becoz of ur livestock? If u keep fishes like angel, ur coral will be nip and eaten. Anyway what type of coral do u keep? Some coral dun do well in captivity and will melt away within a short period. Try ez one such as mushroom, zoa

better to use a sump bro

take my advice. get rid of the canister. nobody use canister in marine. i use canister last time, cannot make it. get a sump much better

since ur tank nothing much. y dun u restart.

and invest in a good skimmer. ur tank is big need a bigger and more efficient skimmer.
