SHH beaslbob! I didn't want him to have that option!
LMAO!
I realize they work, and might be fun if you like to tinker them together, but they're just SO unsightly...it's a personal peeve of mine to have as little technology IN the tank as possible. I like to see fish, rocks, and sand. I'm not say we don't have some "non-display" growout/QT's, but not for the DT's.

Yeah, PVC overflows are unsightly - but they are useful if you are on an EXTREME budget and don't care about how the equipment looks. I agree with yah on that one!

Once Coraline gets on it...and on plastic it will very quickly....you won't even notice it. On my new tank, I purchased a tempered glass tank so it can't be drilled. I never gave it a thought until I read this thread....I should have gotten a reef ready, since I have to redo everything anyway.

I like my CPR overflows once I got a venturi pump instead of the lifter pump they come with. I also like the Ehiem 3000 and 2000 return pumps because it has a dial to control the pumps output. I put all pumps on a single power strip, so if I shut down one pump, they all stop at the same instant. That gives me an extra peace of mind in the event of an emergency, and I need the pumps to stop for whatever reason.
I also like using flex hose instead of PVC, I even have the valves to control flow on them. I can see if they need cleaning, and they are cheap and easy to replace. I don't have any noise except the sound like that of of a running creek which I find relaxing.

I have not read the entire thread but I think something needs to be explained. You always want your overflows to be rated higher than your return pump gph. And not by just a few gallons. Your return pump is at a constant. Let’s say 200gph and if your return is rated at 300 gph you are still only going to return water to your sump at the rate of 200 gph because that’s the rate you are returning water to your tank and overflowing your return. I hope this makes sense to you

well i think that is ur overflow pumps out more water than ur return pump can pump back in....than u will lose siphon from the water in the tank getting to low!

To be honest, USUALLY by the time the water gets to the tank, you've typically lost more flow than you expected. I used to try and match things up so they'd be as close as possible and still work properly, but I found that I usually needed or wanted "just a bit more", which is why I now try to get close, but tend to "overpump" a little, and bleed anything I don't want/need back to the sump. You can always reduce flow via the bleed valve, but you can't manufacture flow that isn't there.
I'm no longer a reefer, so I'm not all about "flow, flow, flow", but I still want to have proper flow patterns in the setups.

im not really that intersted in reefing i just want a nice fowlr tank becuz my son loves to watch and "play" with the fish when its feeding time and trying to find the fish that dont flash themselves as much as the other fish so flow its as critiacal to me....ps i youtubed DIY overflows and they are really long and only seem to be like made of 1/2 inch pvc and that cant do much of a dent in my 90 gallon right? also how would i figure the gph if i made a pcv overflow?
