[brian.julia07]

these are skimmers built on to the back of this tank and im not sure how they work if any one knows it would help a lot!. the only way that ill use these skimmers is if i can make it an in wall otherwise ill drill and by pass the built in sump and put a sump underneath. thanks for any help!!!

They look like they would use a airstone and a air pump, but it is hard to tell for sure.

u might be right with that airstone idea i dont know much about airstones but it looks like those tubes could have had airstones on the bottom.

yeah, looks like for airstone. get a couple limewood ones and maybe a super luft pump and fire it up :)

I'd still fit a sump underneath...

psam if i did a fowlr tank do u think id need an underneath sump then?

techniclly you dont need a sump period, its just always a good idea. I have seen many sumpless reefs, they just tend too have alot more stuff hanging on every inch of the back rim :) Some don't even run skimmers and do water changes often to keep nutrients at bay. That being said i will always run a skimmer on all my tanks
