A few months ago I got a 6ft 135 gallon tank. In the process of getting the tank set up (had to reseal and reinforce the stand) I neglected to plan for a sump. I was too overwhelmed with the newness of a large tank.
Well, now I wish I had. The weird thing about this tank stand is that it has 6 small access doors instead of fewer larger ones. Complicating this is the fact that the whole stupid stand weighed less than 20lbs, and I wasn't comfortable setting around 2k lbs on it without reinforcement. So now between my 2"x6" and 2"x4" reinforcement I have around 7" of free space to get into the stand from each door.
What I've been thinking about is a way to build a sump, or ideally a refugium in the stand, out of something durable, that I can access for maintenance, without removing the tank on top. I really don't want to have to deal with draining the tank.
Here's a pic where you can kind of see the stand.
Any ideas would be appreciated.
