I'm almost four months in and these diatoms just aren't going away. It's so bad that I'll scrape my glass and by the end of the day there's already a light brown mist on them. I don't know what else to do. I'm using RODI water and doing a 10% water change weekly. Is this normal for a tank this age? My Nitrates and Phosphates are low almost undetectable using API tests. Should I be using any special type of filters for my RODI unit or is there anything else you guys might recommend?
Thanks so much for the advice!
