standpipe advise

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?

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".

Here's a link to a tank with a great overflow.

Yup that is the right type of overflow. I would recommend using 3/8" acrylic for the overflow teeth though, more durable and looks better (IMO).

I am also a huge fan of 2" drains, two 2" drains for my display. No way in the world a snail, fish or other reef occupant will clog a 2" drain, let alone 2 of them.

What are the other benefits of using standpipe else than being quite? There are some other ways to stop the noise but whatever i noticed with standpipe since it sucks the water from the top part of the overflow box particules subside and accumulate at the bottom and it is realy hard to clean that crap.

Rob is describing Herbie's silent overflow system. There is a great thread on this at Reef Central that started a couple of years ago.

Definitely go for Herbie's overflow system if you really want silence.

I would use a gate valve rather than a ball valve, much easier to control, I started with a ball valve then changed over to a gate valve and it made a big difference.

With this system you just need straight perforated pipe for both the primary (gated ) standpipe and for the emergency overflow pipe.
