Closed loop help

dtech · 06/28/2009, 11:28 AM

I was cleanning the tank this morning and decided I don't like the look of the Koralia's in there anymore. I have a 75g glass with the standard corner overflow. Here is what I am thinking. Adding an over the top closed loop system (I don't want to take the tank down and drill it0, also changeing the return from the sump to an over the top design with a spray bar maybe. Then I will take the 3/4" return bulkhead and use it to feed some stuff below like a remote dsb maybe or something like that equipment etc.
What does everyone think of doing this? I am currrently in mid project builing new lights so I'm not in a hurry, just want to plan/learn/see others ideas or pics of setups.
Also what kind of pump would you recomend for the closed loop? Lastly tank has mostly SPS, some LPS and a little bit of Zoa's near the bottom and a clam

my build thread has mine. it is/was to be a mag 7

figure 30-40x tank volume for total tank flow. subtract from that what your return pump is doing & that is a good target for the closed loop pump. good thing about the closed loop is since it is equal pressure on suction & return side, head loss is pretty much zero.....just a bit of static loss from plumbing

mag pumps will work, but if it's in the budget, can't go wrong w/ a panworld pump

I was thinking of an external of some sort I like that pump. I am using a Little Giant for my return I like big pumps. what about a spray bar for the return and nozzles on the CL?

Current Tank Info: currently tankless....but planning an AIO
