 |  Pump = Overflow GPH
I am finally going to put a Sump/Refugium under my tank. The pump (Rio 2500HP) will have a 4ft rise, which it is rated for 500 GPH at this rise. I am going to use a CPR 1” Overflow rated at 600 GPH. Will there be a problem that the overflow is rate 100 GPH more? Would putting a loop in the line slow it down a little? Use a ball valve for throttling?
A check valve recommend on the return line, to prevent a vacuum if power is lost?

You will have to adjust the box that is in the tank so that it will work in sync with the pump. You can adjust the box at 1 GPH or 600 according to how high or how low you set it. I would recommend the valve. I would not recommend the RIO pump. Can I change your mind and get you to get a Mag-5? You'll be happier in the end. _________  &&Right now I'm in the middle of a conversion from reef to Discus/ planted aquarium. Hair algae beat me down. Maybe a nano in the future. Everything screwed up so I'm converting to FOWLR. Wish me luck. | |

Yup....I had a cracked housing on my Rio pump but not on the 2 Mag 5's that I have......  But if you have 4 feet of rise, you may need larger than the Mag 5......it is rated at 500 Gph at 0 feet of rise.......
Mag 5 is what I use for return pumps and I like them alot! _________  I Love My Sig By John Hawkins!!!!!!!!!!!!!

Unfortunately I am stuck to the Rio, as I am on a low budget and I already have one. I have experience with Rio pumps and the only problem is I have had (so far) is they are not very reliable on my Bak Pak 2 which I replaced with a MaxiJet 1200. Only way I can switch is if I decide to increase the flow drastically to replace all my Powerheads by using a Water Flow Diverter. If I go this way I would probably need to up grade to a Mag MD9.5 (950GPH @ 0 rise). So many ideas, not enough $$$!
Today I am off to buy my aquarium to start construction on the sump/Refugium!

Sounds good malachi. Maybe you can change those pumps out in the near future. | |
