Can anyone help, I am new too fish tanks, I have had one for a month and I cannot get the water clear. I have a 55 gallon tank with 8 angel fish, I have just done a 25% change on the water and this is the second time I have done it in a month. So every two Weeks. My changes, I do not use tap water I go to the store and buy sping water.my nitrite is a little high but all the rest are good. I thought it was my filter, so I bought a new filter a pen plax cascade 1000 good for a 100 gallon tank it cleared it up alot but The tank still has a haze to it. Any help would be greatly appreciated.
