Ok! At this time ,the tank is basically FOWLR The lighting consists of three 4 ft shop lights with a variety of "coral life" & other fluorescent bulbs. In the tank there is a calcium based DSB & about 180 lbs of LR , More on that later. Internal overflows in the back corners with 1.5 bulkheads & a couple of Koralia# 4's.
The sump has 3 sections & holds an ASM G4X skimmer, a basket of LR rubble, mechanical topoff valve & a mag 36 return pump. All water drains thru a micron sock. There is a seperate 20 gl refugium. It's bare bottom with chaeto & receives water off the return. The mag 36 returns thru a closed loop manifold. I have no idea what this flow rate thru the sump is. I can say it's a lot! About 90% of this setup is diy. More on that later. I was determined to save a buck. Some efforts went well others did not.
This is what a 3 by5 sheet of tempered glass looks like after trying to cut it
I didn't "think" it was tempered!
