Howdy! planning on building a sump for my 276 gal. tank next year and have a few doubts...
1. it wont be against any wall, and i dont want any pipes showing. is it possible to have a water drainage system turned on/off by a valve on the tanks bottom (cut a hole on the bottom glass and seal it with a grid, so only water is drained and not the fish)?
2. is it possible to have a water reservatory for partial WC so i wouldnt have to apply aquasafe all the time?
well, heres a sketch i made to illustrate better what i mean...
