I read somewhere on here that somebody was building an ultra col overflow safeguard. Basically, it involved an electrical relay that required you to push a button to start the return pump. This way if the power went out and you broke siphon in the drain line, the pump wouldn't pump water out...

I had two failures in one day that caused my tank to flood. I was thinking of ways to add fail safes, where possible, to my tank design to prevent future flooding or fire hazards and I know there are lots of creative thinkers on this forum. So list any safety precautions and design features you...

I want to set up an Eshopps wet/dry filter that I purchased about a year ago. I had it running on a small tank in my basement to test it out for about a month and all was good. I would like to set it up on my main 55gallon tank in my living room. The only thing stopping me is the fact that my...

I just ordered an overflow box rated at 700gph and a mag 9.5 rate at 950gph. I figured with a 4ft head height and a couple of turns the flow should almost balance out. I also plan on running a adjustable valve back to the beginning of my sump to bleed off any excess flow. Does this sound like a...

so i came home from work last night to find about 3-5 gallons of water in the stand and some on the floor and a cloudy tank at first i though the tank had leaked but no the sump was low and the tank was just at the top of the overflow. after a quick clean up i started looking around and found a...

I was messing with my system and decided to set up a pump I was not using to increase flow through my display tank. After getting it all going I realised I had not drilled an anti siphon hole as I usually do, so there was a danger of overflowing my sump. I was at the hardware store for last...
