Hello everyone,
I am looking for some help on my 20-gallon tank. I have tried to remove algae from my tank but it keeps coming back even after I scrub all my plants & decor. It is now getting on my live plants. I did once-a-week water changes for a month and scrubbed all plants to see if that would help but it just went back to how it was. Info on tank below.
Light on 8 hours per day, on a timer
1 amazon sword & 1 java fern (planted in January 2023). I have not fertilized but am considering it
Feed very small pinch once per day
Vacuum gravel, change filter & change water (45%) once per month
Use API master test kit, all levels good except nitrate (see picture for level)
Have 1 skirt tetra, 3 guppies, 4 cori catfish, 1 neon tetra, 1 molly
Any advice is welcome!
