Thanks for your reply. This is a brand new 135-gal tank so when we purchased the first plants we purchased a small bag of media from the aquarium shop’s established tanks, and a week later purchased a larger bag of their established media along with more plants.
We’ve been doing frequent H2O parameter checks using API master test kit the entire time, and we’ve now started adding fish. All fish have remained healthy. Minnows ate the white fungus on wood. Algae is growing on the tank walls – as expected. We’ve made no water changes yet.
Does the following mean the plants and bacteria are keeping everything in balance?
Our pH has not changed, at all, since we started the tank - it’s still 7.6.
Ammonia was 0.25 the first two times we tested, but has remained O-ppm for the last 10 tests.
Nitrite tested at 0.25ppm the first 2 times, but it’s been O-ppm several times since then.
We’ve never had a Nitrate positive test since we started the tank.
