Hi guys. I have 3 small tanks I am trying to fishless cycle with fish flakes. I have added flakes everyday or every other day. Size: 28L x 2 14L x 1 Temp 26 C PH 7.6 I put filter media, plants, gravel and ornaments from an established tank at the start in all 3 tanks. API Test kit readings have been trace amounts of ammonia no nitrItes and no NitrAtes. After 10 days I now have O ammonia 0 NitrItes and 5ppm of nitrAtes. There are little snails in the tanks and the water is slightly brackish from driftwood. Any chance the tanks have cycled?
