Options when drilling a tank.

[planbtypea]

So, almost had to get rid of my tank this weekend, actually made it to the FS threads. Got approval to keep the tank if I drill and throw the HOB overflow into the trash. My question is about drilling for overflows. I like the redundancy of the Bean so will probably go that route. Tank is a 60x18x24. I love the look of coast to coast, but that's A LOT of glass to work with so I am throwing that out of the ideas. Ideas:

1)Retro fit internal overflow box, drilled for 3x1" bulkheads out back of tank

2)Slim internal box that attaches to external box through 2x1.5" bulkheads and has 3x1" bulkheads for drains. Was talking with SPS Coral Store and they have something similar called The Wedge.

3)DIY an internal box from glass and drill 3x1" bulkheads out the back.

Leaning towards #2 since there is no silicone to cure, allowing me to get the tank drilled, set back up, and running again hopefully in 1 day. And less holes being drilled... The internal box is about 16L x 5T x 1.5D, MINIMAL lost space and/or shading.

According to the Bean Flow Calculator, 1" PVC at 4-4.5ft will allow for 2000 to 2500gph.

A glass-holes kit would probably be the easiest for you to DIY.

i like option number 2. sounds like something similar to one of those ghost overflows.

Coast to coast is not difficult..I got my glass at meldon glass.in.Lancaster..he's.Very reasonable..

Also I have some diamond bits you can borrow

#2 is similar to the Glass holes overflow but I think the glass holes overflow is higher quality and slimmer in design.

I'll have to look them up when I get back into town Friday. Do you know if the do bent glass by any chance so it would be 1 piece?

Will hit you up for those when I am ready.... want to do it for me? LOL....

Cant fit a herbie or bean in there unfortunately. Did think of them, heard they are hard to get quiet too.

Bear in mind on a tank that size you really don't need 2000+gph blasting through your sump.

True, I figured I would lose some gph with turns in the drain as you do with a return. Or is that wrong? Figured on around 1000-1200 going through it. Also figured that when I buy a house in the next year/2 the 125 will become a sump/fuge for a 200+ and could move the overflow to the new tank....

Anyone have experience/input on glass holes?

Option not listed is the best
Buy my 180g for $300. Save all the heartache and sell yours..so much easier and better when it's already drilled

Who so many holes? I think one shkjld be good. I'm working on drjllin my tank soon as well. First ibgktta get the glass overflow off. Old school tank builders make those things so deep. Waste all my tank space. Its gotta be 7-8" deep. Gonna do a slim overflow up top so I have the surface for rock/coral. Looming forward to seeing what you do.

I'm running a glass-holes nano on a 35g with about 200gph running through it. It does have a bit of a gurgle to it, but it's not that loud. The kit is complete and easy to use, the craftsmanship of the overflow itself is second to none.

LOL, 2 problems though: 1) It wouldn't fit where I have space for a tank. 2) I had to beg my apartment management to let me keep the one I have. They would FLIP if I moved in another, bigger tank... It is a sick tank though...
