Hi thank you for all the replies. I hope my water is not too bad. I used stress coat with the water changes. I am in petsmart now. Getting seachem prime. Not seeing nitrite test kit. I have one at home but it is like 10 yrs old. Thinking Ineed a new one. My biowheel spins a lot and there is a bunch of algae stuff stuck to the edges of the tubing and where the water comes out. Am hoping my bio filtration is ok. Will stop changing media. Thought it needed to be done for the carbon and it is one piece in this filter wondering about these seachem alerts? It monitors levels? Getting the prime and going to another store for nitrite tester. Strips bad Iguess.

Thank you!
