Started feeding twice a day, algae growth is definitely up, but still zero nitrates.As far as ALK burn, I stopped the Kalkwasser drip, as I couldn't get it to be a consistent flow and having to fill it up every day is a bit of a beating. Now I'm dosing 15ml Seachem Fusion 2 after lights out and testing every morning between 9a-10a to see if I can find the sweet spot. Letting CA go for now as I'm convinced my testing chems are no good. There's no way I add no CA for a week and the levels bounce back and forth from 400-600, right?
Yeah, that's a funky Ca test. Get a new one.
Remind me what are you doing for water changes and filtration (reactors, skimmers, Etc)?
