I SETUP MY FIRST MARINE REEF TANK IN 2007, ITS A 5FT X 2FT X 2FT GLASS TANK WITH SUMP, HAD TO MOVE HOUSE ABOUT SIX MONTHS AGO AND SELL FISH + CORALS BEFOR AND BREAK DOWN SETUP ! IM GOING TO START A PLAN FOR NEW SETUP NOW AND ANY HELP WOULD BE GREAT. THE PROBLEM I HAD WITH FIRST SETUP WAS :- CLOSED LOOP OCEAN RUNNER 2500 PUMP WOULD MAKE A LOT OF NOISE SO WOULD NOT USE FOR CIRCULATION, ONLY FOR PARTIAL WATER CHANGES.
ALSO I NOT HAPPY WITH THE LOSS OF FLOW FROM OCEAN RUNNER 6500 TOO THE UV, HYDOR FLOW RETURNS ARE VERY SLOW, CAN THE 6500 AND HYDOR FLOW RETURNS BE USED AS PART OF A CLOSED LOOP TO MAX THE CIRCULATION IN DISPLAY TANK ??? I DONT WANT TOO MANY POWERHEADS IN DT BUT WANT A HIGH TURNOVER.
ANY HELP WITH SETUPS WOULD HELP, SYSTEM MUST BE 100% POWER OUT SAFE. I HAVE MADE A PIC OF FIRST SETUP TO SHOW HOW IT ALL WORKED, SO YOUR PICS IDEAS FOR A BETTER SETUP WOULD BE GOOD. THANKS

The OceanRunner pumps do not make good closed loop pumps unless the tank is small. You may want to consider looking into the Sequence Reeflo series pumps. These are external and feature high volume, relatively low pressure turnover. I would at least consider the Dart pump, maybe even the Barracuda. In any case, I wouldn't shoot for less than ~3600 gph from one of the low pressure pumps. High head pumps aren't really desirable in this situation, FWIW.
 
ok thanks, will take a look at them pumps but i dont have much cash to setup again, i did change the OR2500 for a newjet 3000 and was no better, i still have all pumps and two seio M1100 4400 L/HR p/heads but just want to get the very best of what i have and only buy new pipe work to get this all going again.
 
The setup seems power outage-safe, but that really depends upon how deep your spraybar is underwater. Minimal depth should make it perfectly outage-safe. The closed loop is automatically safe by principle. Your setup, however, still seriously lacks in volume. You wont really get the water movement that tank needs without additional powerheads or a larger volume pump.
 
had a look at sequence reeflo dart online, can only find on us site so not for sale in uk ! i do understand and i will get a larger volume pump asap, but how would you setup the system if say i could get a pump about the spec. of the reeflo dart ? and using other pumps ???
 
If it is similar volume, then I would look into several outlets (~4). If you can find something to alternative the flow between those outlets, all the better (not sure what is available in the UK in terms of this). Will the hydor outlets support that much water flow? You'll probably have to find something different.

Edit: Nevermind. The hydors won't support anything near what you'll need. They are only rated to 310 gph US.
 
what if i drilled two more holes and had about 4000 gph(us) pump to 4 hydor flo outlets on a closed loop, only ask this because i like the hydor flo and the fact they give a lot of water movement without using any power ie;- another expensive unit that will add to running cost ! if i had thousands more cash i know i could buy better pumps and fancy wavemaking units, only been on the salt side two years now and i still have a lot to learn, just my biggest challenge really is to keep cost down. did read books for six months before i buy 5ft tank, they all said get biggest tank you can afford lol :)
 
You can try that, but remember, you'll still only be able to get ~1200 gph US through that many outlets with the Hydor flo deflectors on. Maybe place those on a couple of outlets and see how they work and use something to divert water flow in the others (like loc-line). With a big step up in volume, be sure to increase the diameter of the PVC you are using. I'd use at least 1.5" for that kind of volume.
