Fish Tank Drain and Tank Design

[gurujeff03]

I currently have a 65gal freshwater glass tank 36x18x24. I'm looking to replace it with a similar size acrylic tank so I can put a drain in it. The biggest pain of the glass tank was siphoning water out and filling the tank. I plan to plumb the drain to the outside and run a water line over to the tank.

I would like to put the drain on the bottom of the tank and just plumb it with a ball valve. My question is what type of drain and what size of drain should I use to make sure it seals on the tank because it will get the full tank pressure?

Any thoughts?

The only bit of advise i can give you is that you can drill the glass tank you have now

Why not just use a Python water changer to make water changes easier?

is this just to drain the tank, or to perform water changes? i would just drain the glass tank you have and drill that, if your a good DIY then its not to hard with a little research, and you could maybe put a ball valve like you said but then on the bulkhead on the inside tank side put a screw adapter, so you could screw/unscrew for draining a pipe towards the tops of the tank so it could be a sump overflow, so not only do you have a drain but a overflow for a sump. and on the outside part of the hole put the valve and a screw adapter after that so you could either have it piped to the sump or unscrew and drain the tank. thats half the battle of having a sump. i could illistrate if that doesnt make any sense.
