Tubing and and Cavitation

seacowboy · 12/06/2006, 12:33 AM

Hi for my 20 gallon tank and 10 gallon sump I am planning a mag 2 for the sump return and a mag 5 for closed loop.

I some questions about tubing and cavitation and bulkheads

1. For the Mag 2 it has 1/2 inch inlet and 1/2 inch outlet
what size tubing should I use for the outlet? should I keep the 1/2 inch or should I go up to 3/4 or even 1 inch? Will any specific size tubing be better for protecting against cavitation or with a smaller pump like the mag 2 is cavitation not such a big worry?

2. For the mag 5 and the closed loop
the mag 5 has 1/2 inch inlet and 1/2 inch outlet
I am planning on using 1 inch bulkhead and 1 inch tubing for the inlet. I want to have at least 3 outlets. What size should the outlet tubing be? I assume that it will be something like 1 inch and then I will put some Ts and then the tubing will be smaller. or should the tubing size be the same even after the Ts?

Bump and also

all of you who use either the mag 5 or mag 2 can you tell me what you use?

No one uses these pumps. I highly doubt that.

also is pvc better than flexible tubing with respect to cavitation or in any other way??
