My current 30 gal is stocked with SPS frags and a 1.5" SB,it has one of those crappy HOB overflows that i'm always having top mess with.The glass is also scratched up too,sucks for taking pics so i figured its time for a new tank.
I'm building a new stand for my new 30gal.It will have enough room to accommodate my old 30 underneath it to use as a sump(temp refuge).I had it drilled and installed an internal overflow.This system will have just enough sand to cover the bottom glass
So,what would be the best way to do the switch?All ideas are welcome.
