I have a 55g aquarium with a variety of freshwater fish (about 20).
The nitrate levels are dangerously high. I've vacuumed the aquarium twice in the past week, and added Nitra-Ban three days ago, but, there is NO improvement.
I took the charcoal out of the filter, because I've been medicating the fish, too.
I can tell this is negatively affecting the fish, but, what can I do to improve the situation right now? My tap water tests fine, but the water in the aquarium is nasty.
Should I empty half of the water out of the aquarium?
Thanks so much!
