Hi

I have the BFG of IBC systems - have a look on the systems.

Anyway I have a 40mm siphon running from the 7000 litre Main tank into my 2000l Sump.

Problem is if the power goes off, or a pipe gets blocked or whatever, the tank drains and fish flap about and 5000 - 10000 litres of water ends up on the concrete.

So what I wanna do is make it so the siphon stops if it gets below a certain point (say 3000l in the main tank AND have it easy enough to start up again.

My current one is a sealed unit so if it stops I shove a pump under the bottom end until the air is pushed out. And no I won't do it by cutting the tank end off higher - as I am relying on it being fairly close to the bottom for detritus removal.

I have an overflow running into the sump set up already for if the siphon stops.

Anyone got something similar? plans?

Would be much appreciated

Yeah, sorry I don;t really get it....
