I have an overstocked 10G tank with 2 fancy goldfish and 2 guppies, planted with hornworth and anubias and java moss. I will be getting a 75g soon, but it will be a few weeks until i can trasnfer the fish. Filters are Aquaclear 20 with Sponge, Biological filter, and fine filter (removed the carbon). Everything was well untill last night i did a water change (i do 50% every 2 days, but recently doing every day).
After a few hours, water was white. I panicked and changed 90% of the water, tried to clean the plants and the Malaysian Wood, but some white would persist. Did not clean the substrate which is black very fine gravel (or sand) ecocomplete. Added 50% water, and as water was cloudy, did another change and cleaned the windows, and added water completely, then re-added the fish. Changed out the fine filter media, cleaned the sponge and bio with the old tank water, and cleaned the Aquaclear 20
It was better, but still milky today. I already fed my fish today, but planing to not feed them for 2 days, and doing 20 - 50% water change everyday. Should i be buying anti amonia products or filter media today (will test the water tonight). I normally have some traces (the lowest level after 0) of Amonia and nitrate. Pls give suggestions, as i am in the panik mode. Thanks in advance.
