If your focusing properly, the problem could be movement. Try turning off your return pump and powerheads. If your shooting with auto modes, try setting it to the sports setting, this will utilize the fastest shutter speed possible for the given light. It's also been suggested, but try putting your camera on a tripod and always shoot 90degrees to the glass..this will eliminate distortion.

A good trick that I learned is if you have a timer on your camera. Like mine has a 2 sec and a 15 second timer, I put it on the 2 second timer and I find it takes out the blurryness. I hope it works for you.
