Ok, i just did a 25% water change in my 55 gallon tank since i noticed my ammonia levels were going up again. I had it at 0 for one day and it started to rise over 0.5. I put in ammo-lock once i was finished so hopefully that will help reduce my levels. I have my two filters running, a power whisper 60 and 30, now do i need my bubbler in there or no? My cory catfish and others like to play in the bubbles and when they get caught in the stream the skyrocket to the top of the tank and do it again, its actually funny, but im afraid they might hurt themselves, any idea? Also when i drained the water into a big cooler i have, the water had a slight green tint to me, my tank is still cycling since it is about 3 1/2 weeks old, and it is still a bit hazy, could this be algae or just the haziness of the water and if so can i add an algae clear solution or could i hurt the tank if i do not have algae. Thanks
