Question about RD3 230w pump
I recently purchased 2x 230w RD3's for closed loops for my 475g build. I am currently trying to decide how I want to use one of the pumps. One will be a loser loop over the top through 2x seaswurls. The other is where I need some help. I have 4x 1.24" holes through the bottom of my tank. Would you use a oceans motions flow diverted for these holes or just run the pump through them with no flow diverter. If I did no oceansmotions I would run the pump on a apex to ramp up and down throughout the day to get random flow. My question is can the rd3's tolerate multiple ramps through the day. Say every 3 hours change intensity. I don't want to shorten the life of the nice but expensive pumps.

You'll be fine ramping them, I'm sure. Mine has been on basement return pump duty for a bit over a year and is effectively silent. Scott/Sleif has at least one 230 on closed loop duty and seems quite happy.
Ha! He beat me to it! If I remember, Scott has his program available to view on the Reeftronics site. |

Hey Scott. Old thread and don't know if you will see this. Do you happen to have any pictures of your closed loop. I am most interested in how to plumb the returns in the aquarium. I want the returns hidden in the rock and able to keep detritus suspended.

My RD3 230 closed look comes out of the pump into a 2" union ball valve then goes up to a 2" T fitting. That splits off into a pair of 1" lines that enters the bottom of the tank through the center overflow via a pair of 1" bulkheads. Those lines connect to a pair of 1" bulkheads on 2 sides the 4 sided overflow. On the tank side of the overflow I have a pair of elbows that send the flow downward. At the base of the overflow on the bottom of the tank there is a 1" pvc pipe that circles the perimeter of the overflow. It has 1/4" or so sized holes drilled in it about 1" apart all the way around the overflow. Those holes are drilled to face the sides of the tank so the flow is sent across the bottom of the tank below the rock. There are 2 T fittings in that pipe that connect to the closed loop lines coming out of the overflow.

So from the sound of it I'm guessing bare bottom. Mine will have sand so
I can't have a lot of direct flow across the sand. If I was going bare bottom I think the holes blowing across the bottom would be perfect. I'm going to plumb up my CL when my PVC gets here and try a couple of ideas in the tank to see what gives the flow I want/need. I may try that idea with a slight upward direction to see how it moves the sand. |
