I have a 30 gallon tank with 20 gallon sump. Total water volume about 30 full gallons because of rock and sand. I have SMR-1 with pellets and my Nitrates are still 30+ after a good month or more on pellets. Nitrite and Amonia is 0 not worried about PO4 because this is a FOWLR tank.
DO I maybe need to add more pellets?
WC are 5 gallons every week like clock work
I have a small leak on my 2 inch bulkhead leaking from my sump to my pump. The leak is from where the piping glues into the bulkhead. As to not have to replace it and the ball valve could I seal around where the pipe meets the bulkhead with epoxy? If not epoxy what? Or am i doomed and need to replace the ball valve and bulkhead?
