liverock made of foam??

It will have beneficial bacteria, just not all the way through the rock like typical live rock. The closed cell design of the foam does not allow for it to house the bacteria all the way inside. Your other stuff probably does though, unless it uses closed cell foam.

The pond foam is also a sealant so I would assume that it uses closed cell foam.

Regardless, if I have tiny crevises in which water can pass through them in some way or another then the bacteria that grows in them will be benefitial and aide in filtration...?

So my structure does provide some type of filtration and it is not completely ornamental...?

Thanks,

We should do a agro workshop after one of the meetings, that would be pretty sweet.

We did that a few years back. I missed that meeting though, wish I could have went to it. Texreefer (Mike) did the demonstration. It may be worth doing again later on down the road if more people are interested.

Yes, Rob, it should provide some type of filtration. BUT it does not match the amount of filtration live rock can at the same volume. Most of the foam filtration is on the exterior (even the exterior of all the indentations). Live rock is pourous throughout, allowing a lot more area for bacteria to live on and thrive.

Thanks for the clarification from all of you, TexReefer, Lonestar, Scorpino, CapTexas, JimD etc....

I think the demo would be cool and I'd be interested in it further down the road.
