standpipe advise

Will you be incorporating an external overflow? A nice glass top or cap over the external overflow really quiets things down. 2" drains also pretty much guarantee you will never have a wet floor (well at least from the overflow).

How would I go about cutting the glass for an external overflow? Can I use a diamond bit in a dremal?

Ok you are doing it yourself. I would get some glass pre-cut (or score it and snap it yourself) and then go from there.

Take a look around at a few different designs. I can post a few pics later if you like. It really makes the inside of the tank more natural having one, and removes the clutter freeing up more real estate for coral.

What type of corals are you planning on keeping? Will you be incorporating a closed-loop system?

It will be diy. I already have the tank so I'd have to alter it myself. I assume I would have to grind an overflow into the back panel? I have an acrylic tank done this way but not sure if it's possible with glass.

With a PS4 I would run 1- 1" and 1- 1 1/2" in your overflow. The 1 1/2" will be your emergency drain with a standpipe about an 1 1/2" from the top of your overflow. The 1" should come half way up your overflow, and have a ball valve on the outlet to regulate the flow. Adjust the flow on the 1" so water just trickles into the 1 1/2" standpipe. This system is totally silent with no bubbles.

Rob, what style of stand pipe are you using again?

[Reefer Rob]

I use a Durso for the long standpipe (you can still get a bit of gurgling from it) and just a straight pipe for the short one. I have a 3/4" and a 1" in each overflow, because that's what the tanks drilled for, but I'd be much happier with 1" and 1 1/2".
