Looking for some advice. I can't seem to keep any nitrates in my tank. All levels are at 0, ammonia, nitrite, and nitrate. Specs below for what I am running.
50 Gallon bow front
Community tank. Mollies, Guppies, Gourami, Rummy Nose Tetras, Clown Pleco, and a few snails. The Mollies and Guppies have produced well over 100 frye in the last few weeks. Separated them to grow out tank.
Tidal 55 (Throttled back to about 50%)
Hygger programable LED light (On about 8 hours a day)
Sponge filter that runs at night when the lights shut off.
I do have city water but treat with water conditioner and test for chlorine during water changes.
Introduced Easy Green about 4 weeks ago. Have been dosing per the instructions 2 to 3 times a week to get the nitrates up. And they remain at 0.
No Co², gravel substrate with root tabs
What am I doing wrong? Plants are still growing, very slowly. Ferns have sprouted several new rye zones. Variety of ferns, amazon sword, anubias, and a couple banana plants. I have tried a couple different floating plants but they have died. Also tried a few carpeting plants. Between the lack of growth and the Mollies, no luck.
Help! Please and thank you!
