UV sterilizer...


Seriously, drop in a UV and you don't have to worry about ick, unless you let your tank get away from you.

Ick parasites can be larger or smaller, depending on lots of things. Typically ick is caused by tank temperature fluctuations, which causes stress. I've read that ick is present in all water... but, stress causes the fish to be weak enough to succomb to it.

Keeping your water temp constant is critical in a reef or any fish tank for that matter. Bright high wattage lights have a tendancy to heat up a tank and cause that type of issue.


what is different in his tank?

New light?

New fish?

New rock?

Temp changes?

If nothing, then he put too many fish in his tank and it is at the high nitrate period of the cycle, causing stress and fish death...

Patience is the key to a good salt water fish tank... Rush your tank, and flush your cash down the toilet.
