Hello. I’m hoping for some help. I have a planted low tech tank with Java fern, Java moss, cryptocorne, Aponogeton crispus, Java sword, bacopa caroliniana, petite anubias and some pothos coming out of the tank. The tank is a 20 gallon long with a stingray light. I have aqua soil, crushed coral and a sponge filter. Temp is 77-82. I have new plant growth and thought my tank was cycled. Tank is 3 weeks old with 1 nerite, 1 mystery and 3 guppies. Parameters were looking good until I tried to place root tabs. I didn’t know to punch a hole in them so they wouldn’t float. They all floated and dissolved pretty immediately. Since then nitrites are reading 1.0, nitrates 20-30 and ammonia 0. I am doing 20% daily water changes with fritz complete as a conditioner and adding fritz zyme 7. I am feeding 0-1 times per day. Nitrite goes down to 0.25-0.5 with water change and is up again the next day. Thanks to all those who read this long post. Any help/advice is much appreciated!
