Just thought I'd share this experience with the group.
I've fitted myself a sump on my 90 gallon consisting of a 18 gallon RubberMaid container with a MagDrive return pump and a LifeReef overflow box. All the plumbing, valves, pump, overflow etc. worked great first time - no leaks!
I have set the return outlet such that the back siphon (if the pump stops) would not overflow the sump. The only worry I had for a few weeks is if the siphon 'broke' then the pump would overflow the tank.
So last night I fitted a float switch in the tank wired to turn off the pump if the tank level rose by about an inch. I then decided to test the failsafe features...
Holding up the float switch stopped the pump. Now, with the pump stopped, the water back siphons down the return until this siphon 'breaks' as the return outlet gets exposed above the water. All worked perfectly... then I saw water under the tank stand!.....
Much panic and mopping showed the problem - at the top of the RubberMaid container by the handles are two small holes - the water had risen to this level and was cascading over the floor...
...
Pretty obvious mistake, pretty obvious moral to the story.
If someone could just explain to my wife how small an error I had made then all will be well...
I love this hobby - you have to be expert in Physics, Chemistry, Biology AND psychology!
