I had been running a Top Fin filter, but it broke suddenly, so I had to switch to a new filter in an emergency and got a Marineland Biowheel 350. I put the old filter media from the Top Fin filter into the new one for two weeks, but it caused the filter to leak because it was too tall and condensed water dripped out, so eventually I had to take them out. Now, when I test my water, I have a nitrite level of 5ppm, and low nitrate and ammonia readings. To treat, I have been doing 30-50% water changes daily and adding Prime, Stress Zyme, and Quick Start. The fish seem happy and healthy (once I realized the nitrites were so high, I added another air filter to oxygenate the water more), but I'm concerned the fry in the tank will not survive and that the natural tank cycle isn't happening for some reason. Even after 5 days of daily water changes, nothing seems to be changing. Help!
