I'm getting ready to plumb the tank and have some questions, if yopu'd be so kind...
Here's what I'm dealing with: 2 x COR-20 pumps and a 40w UV servicing a 110 gallon tank with 2 returns.
If I have one pump feed one return, and the other run inline through the UV and then to the return, the latter will have less flow as dictated by the restricted flow for the UV to be effective. So the returns will be unbalanced.
Do I:
a) merge the flows before they get to the returns?
b) split the UV off on it's own parallel circuit (like a manifold), with flow to the UV restricted with a gate or ball valve, and then back into the return line further downstream
c) service both returns with one COR-20, and use the second COR-20 strictly for the UV, with it's output going into the sump return area
d) something else?
