Hi guys, I currently have a 220 gallon freshwater set up with 2 18inch peacock bass and a 22 inch gar. I have been battling nitrate problems for a long time which seems to be very common among all of us. They sit around 80 ppm and I have tried everything in the book except plants, due to their high maintance. I am finally ready to give them a try but need help. I have done alot of searching around for what is best but thought I would just ask you guys with all the experience. I do have a 30 gallon sump tank underneath that is truly just there to catch debris from main tank and to hold my water heaters. I was thinking about filling with some type of plant. I have heard good things about moss balls due to their low maintance but how many would I need for this? I know there are java moss balls and other types. Maybe a different kind of plant? Should I just drop them in the main tank? Any help would be greatly appreciated!! Thanks everyone!
