World's most impatient person (me) waiting for the sand cloud to settle. Came home to find that my husband had taken it upon himself to buy me more sand for the 75 gallon and put it in.... he got the wrong stuff.... he picked up aragonite seabed or something like that. He also put some rocks in there... made some kind of structure... cant see it. Sand storm is to thick.... oh and he bought some freshwater crabs. Those are neat, chilling in the 20 gallon for now. And... he bought 2 goldfish... put them in my 20 gallon established tank... guess who has ick. The 2 goldfish....
