Hey guys.
Shawn, if you were asking me in regaurds to the mag pump then no I plan on using an eheim pump. Less heat transfer. I'd like to get away with not having to run a chiller if I can. So looking to minimize heat however I can. In regards to the 1.5" plumbing that would be for the drain line only.
Ryan, yes unions come in all sizes from 1/2" - 2" I believe, maybe even bigger. You only have a single 1" drain inside your tank so the idea of using 1.5" the rest of the way to help minimize any restriction in flow would be a good idea in my opinion. Might as well maximize what you have and make the best of it, so 1.5" will help, especially since alot of your plumbing will be run horizontally. You'll probably want to pitch it slightly to give gravity a hand.
A 1" drain is only going to give you approximately 600gph drain capacity safely. So I wouldn't try and push it any more than that. So typically for the size of pump you'll be using a 3/4" - 1" return line will be all you need. If you want to run a 1" to help minimize friction from the fittings such as the elbows and unions then I say go for it. Personally I'd run flexible pvc pipe for the return line because I think you can do it without having to use any 90's.
One valve on each is probably all you're going to need. I have two on mine so I'll have total control of how much water I send to the refugium side of my sump. Although I'll probably only ever have to use one, I have the other one just in case.
You could plumb the frag tank to the sump now or later, it really doesn't matter. Personally, your sump is a little on the smaller side so I'd leave it for the big tank. But some people like to plumb their display and frag tanks together so they really don't have to acclimate anything when moving stuff over.
Okay thanks. I will go with upsizing the drain line to 1.5" and keep the return line the same size. Now when you say flexible pvc pipe is that the same as like the clear plastic tubing that I use for water changes? I cut some and that is what I have on the return line now. I think it might be different. I will prob wait on the frag tank. It has a hole in the bottom but no overflow so I will need to make one or buy one.
I was planning on doing an internal pump. I need to price some out. Right now I bought a cheapo one for $50.00, its a Oddssea (sp) 700. I needed a pump for the Brute can for water changes anyways. I see that Corey you are going with the Ehiem (sp) pump. Are those a bit morer expensive? What are some other good pumps?
