Ferts w/ ammonia?
I have a juvie angelfish in my 10g that wasn't eating for a couple weeks, I noticed Monday that he was showing some fungus on one of his fins so I pulled him out and put him in a hospital tank with some meds. It's been 3 days and I'm not sure if he's going to get better or not.
I tested the water yesterday and found about 4ppm ammonia, zero Nitrite and 20ppm Nitrate. I'd think the tank wasn't cycled if I didn't know that the tank was cycled a few months ago. I've been using Aquarium Products Planttabs for ferts, the box says that it contains ammonical nitrogen, I thought that was code name for something that came from ammonia but wasn't pure ammonia, I guess that's wrong. I think there's too much ammonia in Planttabs for my filter to process as quickly as it's released. Plants are doing good, growing several inches a week, algea is minimal, other than my angel the fish seemed fine so I thought it was just the angel acting wierd. Now I get to do large water changes daily until the ferts are done releasing ammonia.
So I decided I won't be using AP Planttabs anymore, do all root tabs contain ammonia or are there some that don't?
