Thank you jungle fan for responding. I’ve had the tank running since June with real plants. I added 6 platies in July 01, 2021. Testing with test strips nitrate were at a constant 40ppm with easy green. Nitrites were 0. When I added the rams I noticed the nitrites were ticking up since last Friday. The tank is stocked with MTS, bladder snails, 3 ghost shrimp, 3 platies (14 platy babies), 2 green corydoras, and 3 golden balloon rams. Anubias, ton of wisteria kept trimming and replanting , frogbit and wisteria. It’s a 90 gallon tank with co2.
