IO Salt Question

[Tom R]

Hi Ron

I also keep a power head with a sponge filter attached to it in my mix tank.

I think it a Hagen power head attachment.

i don't want to hijack. But do you people find that the IO kind of mixes up a little "dirty" looking. I find that there is a bit of a tan color to the foam and my skimmer foam seems to turn the same color for a few hours after a WC. And no it's not my water. I've tried other water sources and have had the same thing.

[Flash]

could it be from your sand bed when you WC?
