My tank was has been setup for over 6 months. I did have 7 albino and 2 pepper and 6 sterba Corys with 5 white cloud, 7 Rasboras, 1 clown pleco and about 6 super red pleco babies. This is a 36 bow front. All live plants in bdb
I fed them this morning...not thinking and then did my water testing.
Parameters: pH- 8.0-8.2, Ammonia- 0ppm, Nitrate- 80ppm, nitrite 0ppm....
This tank has been getting water changes about every 2 weeks 10 to 15 gallons. We did miss 1 recently. We had a death in the family and we're dealing with that.
The Corydoras that died were doing really well prior. I have since added a seasoned sponge filter in addition to the HOB. I also have a UV sterilizer in this tank.
