Agreed. I think this product offers options in the design phase, but adding it to a functioning reef is redundant.

Is this basically the same as hydroton? I know people were using it as well.

MarinePure is just live rock replacement. This is handy for people using artificial reef structures or for other types of systems with no live rock like breeding setups and commercial setups. A tank needs very little live rock in order to process the ammonia produced by the fish. Nitrifying bacteria is very efficient. I wouldn't put this stuff in my reef tank.

I agree which is why I could see using the stuff, if one didn't want a display of live rock. :biggrin:
Just comes down to aesthetics mostly.

just wondering if anyone that uses marine pure has noticed any ill affects to their corals? I read online that it leaked aluminum which made some users corals die.

looking at this option vs the xport bio plate simply because I wont have to saw the minepure in half to fit my sump.

It seems the Brightwell block is getting better reviews on line.
Rich (Bblinks) really likes his, but he didn't have to cut it.
Does it not come in a brick, plate or cubes?

it does, but even with the plate I would have to cut it in half to fit between the baffles

I see your point now. It would be hard to cut it in half if you need it thinner.
Certainly not by hand. And you would need a concrete saw, not a hacksaw, used for steel

hmm

back to the drawing board. maybe i'll just buy the bring then and put it under my filter socks or something.

Pretty sure you could cut it with a hacksaw. It's fairly soft.
