i have a 75 gal and have the sand and mixed water in it. After setting just the water and sand up it got extremely cloudy and i knew this would happen and that it would settle, and it did. So after it had settled and the water was nice and clear i recieved my power heads, 3 maxi-jet 1200's. So i setup the Phs 1 in each front coner aimed up and towards the back middle of the tank and one on the right back aimed across the back of the tank, next thing i know the water is just as cloudy as when i added the water to the sand. Is this normal? i figured it would settle but havent noticed much change since yesterday and was planning to get my LR soon.
