interesting tank i saw

[timdam]

my tank knowledge isn't that great. but i was at this restuarant over the weekend, and they had a really nice tank. what i found interesting, is that the tank had two overflow BOXES at the top of the tank. but they weren't normal looking overflows where it goes to the bottom. they were like two cubes and they never went to the bottom of the tank, visibly. i guess the plumbing was above the tank.

i dunno if that makes sense. but if it does, does anyone else do their overflows like this?

u can kinda see the pic on this page. 3rd pic.

Are you talking about something like this

Yeah sounds like it was something like that or a HOB (Hang on Back) overflow.

 

[timdam]

yes, i guess u can say it was like that. except that it was in the middle of the tank and hanging onto nothing.

I've seen many tanks that employ a central overflow, so you can see in from any side of the reef. It is simply a 4 sided overflow, supported by the drain pipe in the middle of the tank, with the hole drilled through the bottom.

Example:

but that pic goes all the way from top to bottom of tank. this tank never goes to the bottom. it's just a cube box. i guess the plumbing is all thru the top.

can u see it in that one pic on the website?

From what I can see it looks like there might be a pipe that is going down that is hidden by the rockwork. Would kinda make sense since it seems like the rock is all around the center and hiding something maybe?

That's what I'm using on my 180 gallon reef...a 20" x 7" x 4" overflow, with two 2" bulkheads drilled through the back of the tank. I end up having much more room towards the bottom of the tank for live rock since you don't have the full length columns. Check out glass-holes.com or 4coral.com. They sell those overflow boxes.

BTW, I think that's what you are referring to based on your description. The link on your post (http://www.h2sr.com/goldfish/goldfish-gallery/) doesn't work (server unavailable) so I wasn't able to see your pic.

R2nj, the link works fine when i click on it. maybe you can try it again.

travis, no pipe goes down into the rock. u can only see one box in the pic, but there are two boxes in the tank.

also, the pumps that bring the water into the tank from the sump were coming out of this cube too. not sure if that info helps.
