Good morning everyone,
I am batting an issue which I just need advice on. The tank is a 40G breeder and has been running for 4 weeks now. Tested the water before adding fish which showed the cycle was complete. Adding in plants recently and a dozen cardinal tetras. Fast forward to this day I am down 5 cardinals and counting daily. I tested the water today everything checks out PH 7.2, Hardness 75, Nitrite 0, and Nitrate is just slightly showing 5. Temp is sitting at 77 degrees. I currently have bog wood as the driftwood of choice, eco-complete, and gravel as the substrate. The filter is an aqua clear 40.
I am seeing free-floating particles which can be a small breakdown of organics in the tank I am gong to put some filter floss in the filter to capture that.
Any thoughts or advice on the matter, I haven't had an aquarium in 4 years so getting back into it has been a little bit of a learning curve.
