questions re: hole drilling

[digital-audiophile]

Have you thought about putting in an overflow box and drilling the drain/return lines on the bottom to go Herbie style?

Herbie Style?

Anthonie, My other option might be a wave box or some other kind of higher end flow maker. I already have the pump for the closed loop so I'm exploring that option first.

Herbie is the best thing going right now

I keep linking to Richards build thread because it does an awesome job of showing how it is plumbed http://canreef.com/vbulletin/showthr...ghlight=herbie

Here is the reef central link that created this style http://www.reefcentral.com/forums/sh...hreadid=344892 lots of reading if you are up to it.

Basic concept though is the tank is drilled with three holes on the bottom of the tank in the overflow. Two holes for 1-1/2 pipe, one is the primary drain that is throttled with a ball/gate to eliminate and splashing, gurgles bubbles etc, the second is an emergency drain line just in case the primary is blocked for any reason. The the third hole is for the 1" return line. Take a look at Richards pics they show really well how it is plumbed.

You are more than welcome to swing by my place to see how I have mine hooked up if you are interested

Hmm, interesting system. I might have to consider it.

I just spoke with Bow Valley aquariums and they recommended that I don't drill closed loop holes in the side glass, too thin. They did say that the bottom on my tank was sturdy enough for those sized holes, so I start thinking about a new design.

Digital, I might have to come over to see yours after all.
