When I ask people how to fix this they always say “siphon it” but here’s the thing, I do siphon it frequently and get most of it out each time. I normally siphon once a week sometimes more but it always comes back a day or two later. This is in a 5 gallon tank with a betta. Is this from my spider wood? Is there any way to get rid of it more effectively? It’s driving me nuts! I know it’s not algae bc I do lots of blackouts and it still happens! My water parameters are good with 0 ammonia and nitrite and it always stays between 5-10 ppm nitrates. Also is that enough nitrate for plants? I think I have a nitrogen deficiency bc my plants have yellow old growth. But here’s the thing, I can’t go more than a week without water changes or else my tank looks like it hasn’t been cleaned in years bc of this stuff. How can I completely rid this?!?!
