corrosionjerry Posted December 30, 2010 Report Share Posted December 30, 2010 I purchased a HQB-3500 pump a couple of years back when I had the brain fart of moving my ro water mix directly from my conditioning barrel to my Discus tank that was about 40ft away / it has a H-max of 3.5M at 3000L/H / never used the darn thing even once.... I am guessing that this is going to be to powerful to use if I put together a sump tank that will be about 4ft below the mother tank / is there some way that this thing can be toned down if it is to powerful? I guess at the very least I should be able to use it in my barrel when I get some live rock to cure or will it be to terbulant for even that?

jvision Posted December 30, 2010 Report Share Posted December 30, 2010 That is a beast! I'd try to make a few outputs in the tank - you should be able eliminate all dead spots! You can also T off thru a UV filter, you can use the pump to run your skimmer, and you can run a T back to the beginning/middle of your sump to bleed off excess pressure.

corrosionjerry Posted December 30, 2010 Author Report Share Posted December 30, 2010 LOL / yep to big..... Think I may have to do a trade of some kind / sort of thought it was a little big looking at the pond picture on the side of the Box Quote Link to comment Share on other sites More sharing options...
corrosionjerry Posted December 30, 2010 Author Report Share Posted December 30, 2010 What size of pump should I be looking at for this kind of application L or G an hour Quote Link to comment Share on other sites More sharing options...
dunl Posted December 30, 2010 Report Share Posted December 30, 2010 LOL / yep to big..... Well....yes and no. Depends on the setup you are making. I have a 1200gph pump in my 55g tank right now - no sump. :shifty: But I blocked all kinds of live rock in front of it to disperse the force of the flow.....lots of good flow throughout the tank, but not blowing everyone around. You'd have to be very creative to use that in a normal 4ft or so tank. Guess you better upgrade to a 320g or something. :thumbs: Quote Link to comment Share on other sites More sharing options...
bosshog Posted December 30, 2010 Report Share Posted December 30, 2010 800 gph is not too much flow in a reef tank. I'm running just under 2000 gph in a 24 gal. It is not excessive. Try using two or three outlet points back into the tank, should create nice flow throughout. If you want to throttle the pump back put a ball valve on the outlet side (not the suction side) and set it wherever you want. A smaller pump will be more economical in the long run.

dunl Posted December 31, 2010 Report Share Posted December 31, 2010 Bosshog is correct, and I missed something....3000L/H, not gph. So yes, 800gph should be fine for you. Quote Link to comment Share on other sites More sharing options...

Nah the LPH is Fine I run a 950GPH return and a 1200 PH and thinking of adding 1 more for dead spots on a 90G .....what worries me is you say a pic of a pond on the box?......pond pumps don't usually work on reef tanks there is sometimes non stainless screws or metal shaft that will rust is SW Edited January 5, 2011 by Murminator Quote Link to comment Share on other sites More sharing options...

Here is what is says... What do you think? Shell is made of quality stainless steel or plastics Axle cores and casing made of quality ceramics and are waterproof Motor and wires are sealed by a special resin Insulation Quote Link to comment Share on other sites More sharing options...
jvision Posted January 6, 2011 Report Share Posted January 6, 2011 I've used pond equipment for SW applications in the past. As long as it's the good stuff, and not cheap Box Store brands (I'm not a fan of Laguna pumps), you should be fine. I'd use it. Quote Link to comment Share on other sites More sharing options...
