liverock made of foam??

[Mr Cob]

Wrong,, Bacteria will only populate the surface,, this is a closed cell foam. nothing gets in.. It will not ever act like live rock no matter how long it is in the tank.. but it does look really cool

Ok...I said .....

"If your foam is coarse as mine is with lots of crevices and little caves it will become "live" eventually if seeded with actual live rock...??? Right?

Note: I distressed my black pond foam and the effect was thousands of crevises similar to what you see on actual live rock.

So, are you telling me that those crevises...very tiny ittty bitty little crevises will not populate with bacteria?

That doesn't make sense. I agree with you about the purpose of the foam as a sealant and that stuff will only grow on the surface....but I did not defend the regular surface foam, I defended my distressed pond foam with thousands of crevises.

I'm also only replying further as to find an answer and not actually flame a thread, subject or person.

I'm very curious now wether my pourus foam is acting as a small filtration unit or if it is still in fact ornamental with no benefitial bacteria life despite the thousands of crevices in it.

Thanks.
