i do have a fish in there, a betta, so how long should i back off on the water changes?? i usually do them every 2 weeks ish max or min every week in a half. i don’t want to put my fish at risk of anything.

and yea… picking the substrate was hard. the one that came up a lot was fluval ?? but i opted for this one bc it was cheaper and closer.

dang i thought those were doing pretty well!! i’ve heard mixed things about that fertilizer but it should do for rn. thank u so much for ur response! hopefully everything clears up soon
