Has anyone ever removed the corner flow piece from their tanks? I recently picked up a 75 gallon with a cornerflow. I am too nervous about setting up a sump, so I was wondering if the cornerflow piece was easily removable. Any thought or experiences would be appreciated.
 
Removal is fairly straight forward, however, remember, the hole/holes in the bottom will need to be plugged off. This can be accomplished either by capping the pipes or getting a plug for the bulkhead/s.
Overflows are usually siliconed in place on a glass tank....if this is acrylic, you may just want to leave it and deal with it as you will not be able to remove it cleanly...

Yes, I would cap off the bulkheads. The tank is glass, if I leave in the cornerflow, won't the water behind it get stagnant?

If the silicon is sound, water wont get back there but the water level will need to remain below the weir.....but, since your tank is glass, just take that overflow out and move on....but, food for thought, a tank with a built in overflow is worth considerably more than a straight plain tank. You may consider selling or trading it for say, a bigger, regular tank? Just a thought.
 
I would definitely reccomend pulling the trigger on a sump! The scariest part is drilling the damn thing and that's already done for you! Something like a 29 gallon would fit well in your stand and you will be able to hide almost all of your equipment in the sump
 
My pre-drilled 120 broke and i had to get into a 180 that wasn't drilled in a hurry..... Hate it so much that i am breaking it back down this weekend (only been up for a few months now) and drilling it so i can put a new refugium/trickle setup under it. You don't have to go as elaborate as that but it def gives you more airflow (no need for air pumps) and also gives you more water volume, and a place to hide heaters just to name a few benefits. To me it's just a win win all around.....
 
You all make valid points. My fears are overflowing the sump and running dry the pump. Noise is a factor as well. That's why I was looking to just remove everything.
