I cleaned the fish tank yesterday, sucking out about 25% of the water and refilling it with new water. I added marine salt, a cholorine eliminator and some liquid calcium for the snails and shrimp. For whatever reason, the water is a little murky today. Every time I change the water, the water is always murky the next day. Usually, two days later, the water will clear up. It never happened to me in California and I’m not sure what it is in the Florida water that does that. I hate it because it looks like I’ve neglected the tank when, in fact, I’d just took care of them!
