Could someone help me please!! I have a 30 Gallon freshwater tank that is well established. The tank has 20 lbs of eco complete soil and 10 lbs of gravel. It has one amazon sword and a aquaclear 70 Hob
along with a 300 w heater. There are mollies, tetras, dwarf gourmis, 2 male bettas (they don't fight at all), guppies, and corydoras. The nitrates and nitrile are 0 and the ammonia is less than .25 ppm
. I do 2 20% water changes per week and clean the filter regularly. I also add heavy amounts of seachem pristine, stability, flourish, flourish excel, prime. Despite this the water is really cloudy and gross. Help!!
