Under gravel filter

[Joeyt66]

I have an under gravel filter in my 65 G as well as a Aqua clear 300( i beleave) i am just wondering how often do i need to clean out the under gravel filter ) i have 2 powerheads running it. Also what is the best way to clean it?

You need not clean it out, really. The point of the filter is to house bacteria to break down detritus. The only thing you need to do is to make sure it doesn't get blocked up, because then it drastically loses its effectiveness.

If your parameters are fine, then the undergravel filter should be doing its job.
