CPR Bak-pak upgrade question

[romain]

I have an idea today. Is it possible to upgrade your CPR Bak-pak from MJ-1200 to Mag 3? Anyone tried this before?

Looking at the flowrate charts for each pump, I don't see much of an upgrade. At 0 ft , the mag 3 pushes 375 GPH while the MJ1200 pushes 295 GPH. The mag 3 also uses 75% more wattage to gain just 27% (80gph) more water flow.

However, if you still wanted to make the move, simply get the correct size tubing to make the connections. The mag 3 discharge outlet is 1/2' MNPT.

With the CPR Bak Pak skimmers, you need a RTV type pump which allows you to draw air from the intake side of the pump. Rio does this with their 600 & 800 pumps and Maxi Jet adds a doo hickey with an airline attached. The AquaC Remoras are different, they use a spray injector.

isnt that already the upgrade cause they come with a rio 600 right atleast i think thats what i started with

CPR Bak Paks come with an RTV Rio 600. The recommended upgrade (by CPR) is the Maxi-Jet 1200 with venturi attachment. For some reason they did not recommend the RTV Rio 800.

Thank you guys for the input. How do you think about this modification? Will airstone help to skim out more? http://www.reefcentral.com/diy/bakpakmod.htm
