Shorten body for 4 recirculating OR2700's?

30? I wouldn't count on that number till there's some solid data on what the pump pulls with what venturi and what mods. Were you going to add it with the Gen-X venturi?

Not sure yet but i think that even with the gen x stock venturi there will be a hugh improvement. What type or brand venture do you suggest or reccomend?

 

[kentrob11]

Well, that's what I'm working on at the moment. It's pretty much been established that the stock venturi for the GenX is crap so I'm working on a few different configurations to see which is best. I ordered a Dwyer air meter so I'll be able to come up with some numbers next week....

man you need to research that
they both pull the same scfh stock 15 vs 16 stock the issue with the nw-200 is not the pump. you could put a 40scfh pump on that skimmer and you will not pull more than 16 scfh theirs other issues, (flow restictions) go read more go back thru the OR thread or better yet the octopus mod thread.

I have already modded the restrictive 90* elbow. And have read all of the threads. what other issues are you talking about.

 

[Roland Jacques]

it has most to do with plumbing ID. i answered the other limiting factors in the octopus thread it may be a little off topic here.

 

[Roland Jacques]

anything new? did you get your flow meter. i think i need to see an ER moded 4100 pump interior so i can salvage my pump.

The Genx stock venturi is crap, i will confirm that

 

[kentrob11]

ya got that right- I am still waiting on my meter- I did glue everything together and got the silencer brackets mounted...

 

[kentrob11]

Well, I got the RMA-22 but am still having problems with the ball bouncing A LOT in the meter. What I think is the best venturi right now bouces the ball from the bottom to the very top continuously- like 2-3 times a second. The ball actually bangs into the top at 25lpm....One thing that I can't seem to do with ANY ventiru configuration is cavitate the pump! Thoughts?
