madweazl February 12, 2015 February 12, 2015 I'm in the planning stages for a new tank (72x202x20) and was planning on using dual DC return pumps. The plan was two run the two pumps off a controler (Reef Angel more than likely) along with a level sensor, then drive them <50% on a daily basis with the ability to have one ramp up appropriately in the event of a single pump failure. My ideas started running wild while I was in bed last night and I started to ponder the feasibility of having the return pumps actually create the wave action instead of using separate pumps (Vortechs). It would keep the display free of anything inside and probably draw less power in the long run (not really a concern but always nice). Any comments on the feasibility of doing this?

Amuze February 12, 2015 February 12, 2015 I think the constant start/stop to create a "wave" effect would cause pump failure, but I'd be interested in seeing if it works.
s2nhle February 12, 2015 February 12, 2015 You also have the deal with the noise from inconsistent water draining to sump.
madweazl February 12, 2015 Author February 12, 2015 My initials thoughts were that the pumps would never turn off, just spool down (cant have anything back syphon) as the other ramps up an equal (inverse?) ammount maintaining a constant flow rate. What I hadnt initially considered was the flow rate since I'm running a refugium; I'll probably be running somewhere around 500g/hr through it and that isnt going to do anything in the display. I dont want to buy another refugium right now (currently an Eshopps R200) but I have seen a number of prefabbed units that have a separate refugium area that might make this feasible down the road.
