I dont know if there is anything written on this, or if its right or wrong, just what I see in my 55, so trying something new in the 180.
As for the grey "poof" that appears when rock is disturbed, In my opinion, there are alot of critters living in the LR. Have you ever noticed little grey piles of sawdust looking stuff on your rock or sand that wasnt there yesterday? I believe these piles are some kind of waste or whatever. That mixed with the waste the fish produce accumulates under the rock where there is no water movement to get it into the water column to filter it out. It just sits there and creates dead spots(I dont think anything can live in there)
IMO by stirring up the sand may prevent alot of waste from accumulating and may lead to a healthier system.
SW65galma - Was unerneath your UGF cleaned regularly?
I think the problem was like a regualr filter, it couldn't handle the waste and just overfilled. I would have had to clean it a lot, which as you know in a 180 isn't the easiest thing to do.
So it's easier to change a filter in a canister or HOB filter than bother with the UGF.
I just see NO reason to bother with a UGF..
I don't see it buying you anything besides headaches.
