Hi,
I have a reef-ready 90 gallon which has the overflow in the back right corner. Inside the overflow, there are two pre-plumbed holes, a one-inch and a 3/4 inch. I assume the original intent was to use the one inch as the stand pipe and the 3/4 was the return. I of course am concerned with not having any redundancy in the overflow to the sump. I figured I would use both in a Herbie setup and then run a length of PVC up the back for the return.
Questions:
Does this seem like the right course of action?
Which of the two existing holes should I use as the primary? The one inch or the 3/4 inch?
Any other ideas or alternatives I should be considering?
Thanks,
Ric
