I am setting up a 200 gallon tank with a 55 gallon sump, how many times should I turn over my tank? Also what's a good return pump and how many gph should that be? Also what overflow box? Thanks!
200 gallon tank how many gph

With this 1500 overflow box? I'm kinda clueless about this :/

Turnover through the sump only needs about 3-5x the system volume, so somewhere in the 700-900 gph would be fine for return flow. The Eheim Compact+ 3000 is a good, fairly inexpensive pump that comes to mind, though you have many options. Turnover within the tank itself via power heads would be a little different and varies depending on what's in the tank.

yep... 3-5x sump should be plenty.. some run up to 10x no problem... 30-100x total flowrate (return plus powerheads)..
60-75+ is for high flow SPS tanks,etc..
as to overflow box... can the tank be drilled? IMO the hang on overflow boxes scare the crap out of me.. I could never sleep at night when I had one.. But they can be made "fairly" foolproof..
But a drilled tank (bean animal/coast to coast overflow box or whatever) is FAR superior..

Ok I haven't done anything to my tank yet so I'll have to research how to drill the tank and such, I want the best I can get I just don't want my tank to break.

I like the Simplicity return pumps.

Something like this? I think I'm starting to slowly understand!

Awesome! Now I just need to figure out where exactly to drill the holes!

The 'kits' all come with a drilling template (and some even come with the drill bit). Piece of advice: don't drill the tank until you have the overflow (from personal experience :lol.
Oh that's good! This is probably the most complicated part of getting my aquarium set up haha but I think when this is done then I'll start worrying about water parameters and all that good stuff!

If you want the "best" then read...
http://www.beananimal.com/projects/silent-and-fail-safe-aquarium-overflow-system.aspx
Note you only need the valve on the "full siphon channel" despite what the images show...
and if you aren't too handy then a box like this gets you 90% of the way there.. ok maybe 65% of the way there..

Note that the "coast-coast" overflow box gives you the "best" surface skimming vs a box thats only 1 foot long or whatever.. The wider the box the better it will skim along the entire surface of your tanks length..
It only takes 2 pieces of 1/4" glass to make a full internal coast to coast.. Like here.. first pic I found on google..

I think they meant that the sump should turn the tank over by itself 3-5x the display and then the rest of the movement comes from power heads and such.

Flowrate through the sump should 3-10x display tank volume...
And I kind of doubt there is any real data to back that up other than maybe it came from suggested turn over rates with skimmers..
But in general many have used that as a guideline and not had any problems..
I've run FAR in excess of that too without issues that I could tell..

I have long targeted 3x display volume nominally through the sump ... and I am able to keep a successful tank. Folks who argue for higher rates seem unable to articulate cogent reasons for the higher flow rates; though they can make the same claim of a successful tank :lol:. Bottom line is that it seems to make little difference, so go with what works for you. BTW, some will also argue to match through flow with skimmer pump capacity. Makes little sense though.
