So, I have two tanks- a 20 gallon community tank-not overstocked, and a 7 gallon singular Betta tank. I’m using the same tap water, and I tested my tap water for ammonia- zero traces. My Betta’s water is good. My 20 gallon is a mess. Super high ammonia readings. We’re talking a 1.0. I do many water changes, I add amquel, nothing seems to help. I will tell you that I am guilty of a fish in cycle. I thought I had enough experience to do this without harming anyone, and they seem fine. I cycled my Betta tank properly, and I will never do a fish in cycle again! Here’s the thing-the 20 should’ve cycled by now. What to do? Again, no clamped fins, no staying at the top. They all seem active and fine. This is what is in my tank- 5 plants, 1 moss patch, about 3 inches by 3 inches, a flame moss stone, 3 pieces of petrified wood, a piece of driftwood. A rock cave. I clean out any plant debris, often. Suggestions?
