A friend of mine is interested in setting up a 10 gallon SW
tank. He plans on a Fish Only tank with a DSB
no greater than 4". He has a 100GPH Power filter with bio-wheel. He's interested in keeping only a pair of clowns.
After sand displacement, the tank probably holds somewhere between 8.5 and 9 gallons of water. The power filter alone is giving a water turnover rate of ~10. He also has a MaxiJet 300 lying around. It takes up space in the small tank, is it necessary or should he use that to mix SW
rather than buy a new one for that purchase?
