What diamater of pvc do I need to use for the fuge to the main tank?And do I use the same for the over flow to the fuge. I will be using a Rio 1700 and a 900 ghp over flow. Thanks for the help.
I have a 110G with a 20G sump/refugium. The key for a fuge to work well (especially if you plumb in a UV unit like I did) is to get slow steady flow. I used 3/4 " bulkheads and 3/4 " flexible hose with several valves plumbed in line to control the flow down slow enough for the fuge and UV to work nicely. I used a Mag9 return pump and gravity feed.
