AAC (Autoclaved Aerated Concrete) in SUMP

[Poseidon Black Sea]

Hello i have a question, anybody used AAC (Autoclaved Aerated Concrete) as a brick in the sump, basically like the marine brick , if so why? If not why?

No - and why to use it? old rock works as well (assumedly)

The porous structure sounds interesting, the autoclave part probably means it won't have to cure in water as much as normal concrete.
People say exposure to water is a weakness, but it's not clear if that's just due to freeze/ thaw destroying it or if the water over time actually degrades it.

I was looking at aerated concrete a while back. I seem to remember surfactants being involved in the bubble formation / integrity until set.

so can i use it?

There won’t be any measurable benefit if you did use it in a reef tank because reef tanks don’t need extra surface area, they have an abundance already.

Agreed it can be used to transfer seed any other system, but so can red bricks from a garage or a handful of pillow stuffing, or even a cupful of water from the established reef used in place of bottle bac

all that is the same as using the concrete, use whichever is easier. A cup of reef water is probably the easiest, it has lots of free bacteria.
