30g cube question

[Ross]

I used one before but i dont remember how much it cut down on flow. Is it drastic or not very noticeable?

[JimD]

Im using one on a Mag 12 with about 18" of head and let me tellya, it has plenty of flow! For me, hardly noticable at all.

What do you think about a blueline 40HD. Does 790gph at 0ft of head. Too much?

[JimD]

The sqwd is factory rated at 1400gph and I believe that to be conservative, so 790gph would be no problem. Ive seen them run off Mag 24's in the past.
