hey guys i am new to this forum and fish tanks. i have a 30 gallon fresh water with 3 bala sharks and 3 tiger barbs, and 1 algae eater. well things are going pretty good, my water tests loook good, but i have a problem. my water looks a little hazy and wont go away. if you look really close at the water, it almost looks like alot of microscopic bubbles floating around making ot look hazy. any suggestions would be greatly appreciated. i want clear water.
