The story of my system crash

[dabandit]

Normally you dont,the overflow level will stop it,but the overflow was plugged and the sump continued to pump water into display which was being fed by my brother topping it off. It was filled to maximum which is about 2'' over my overflow,I approximate 12g. Also he must have topped off sump yet again because it should have been able to handle even the extra capacity. It was a fool proof system...or so I thought lol

It was for the best though,gave me a chance to try sps again and a blank canvas lol
