Replacing an established tank... Overflow drain questions!

CNoonan · 12/17/2008, 10:53 AM

Hey Guys.
I just got my hands on a custom build 180 gallon half circle. The cost was a little more than the 144 gallon Oceanic half circle but it seems to be a nicer build.

I will be using my old sump, skimmer, and just replacing the drive pump from my original 175 gallon.

I'm going to write up a nice checklist to keep me organized while breaking down and installing-- but I have a question right now that has been on my mind and I am a little worried about.

The current 175 gallon tank has 2 overflows, 2 drains, 2 returns.
This tank has one 1.5" drain, and one return.

When I bought the tank it wasn't rated at a GPH. I want to put a 1800 GPH MagDrive in the sump to drive the tank.

Do you think the tank will either drain too quickly or fill up too quickly?

I'm worried... :-/

Thanks RC!
