I'll do without the 90's on the pumps, thanks HammerSandwich.
Also I don't think fan noise will be a prob? They're low CFM.
Just a quick question,
Do you guys think my system is geared for high flow?
And would I benifit from higher PSI instead (Pumps pumping together with Y connectors)?
Maybe I should be using Y connectors?
Does anyone have first hand experience using 3/8" / 2 block / 2 pump systems or similar?
