Drilling holes/set-up

[LetItReef]

Hello,

How many holes do you drill a glass tank? Is it one of each side for the drain and overflow? I have seen different kinds of set up such as Herbie, Ghost/Synergy. Are these types of brands/set-ups are much easier to work with and much cleaner finish rather than the conventional drilling the tank on each sides?
I hope my question make sense.

Any links on how to's that will be great.

Thank you.

really it depends on the overflow you're buying and or building for the tank in question.
I DIY'd my overflow and only drilled two drains as the returns sit on top.

Would like to drill it on my own too but uncertain if I still need to get overflow boxes.
Here's what I think. Drill one hole the back of a tank on each side- one for the drain and one for the return then plumb it. With doing this do I still need to get overflow kit?
Thanks!!

With an overflow box installed it skims the surface of the water remove particulate from the DT to be removed by things like filter media, socks and so on, if you plan on just drilling and installing bulkheads with say PVC "U" joints it will accomplish that same thing but will be on the noisy side.

Nope, you wouldn't need it.

Size and number of holes does depend on your tank size and the type of setup you are building. I prefer to use larger drains of 1.5" or 2" as they give you the option of putting more flow through the aquarium and are much less likely to clog and cause a flood. An overflow box is preferable as it skims the surface much better than just a bulkhead with a drain screen. Multiple drains are also preferable as you have back up if one should clog. Durso stand pipes work well to quiet the drains as does a Herbie style setup.

I would recommend a minimum of two drains and 2-4 returns to give you flexibility if you wish to modify the setup over time. You could also consider the option of a closed loop for flow. The new Ecotech Vectra pumps can give you lots of changing flow capabilities and provide a clean look.
