Auto top up

Hi all

Heres my auto topup system...its not designed for evaporation (although that would work) but more for the frequent times the power goes out (I live in NSW).

My filter does not have enough reserve capacity to hold all the water that retruns from the tanks and the pipework....I would get a massive flood and more importantly, when the power goes back on the sump would pump dry well before the system got going again.

40 mm bulkhead in the glass sump...I was worried it wouldnt be enough to cope with the overflow but I did a test today and it worked a treat...the bulk head is connected to some PVC piping that goes through the fish room wall

40 mm PVC piping...drains from the glass sump inside the fishroom and dumps the overflow water into a big black Bunings tub (I think theyre 200 litres)

The return pump that is sitting inside the Bunnings tub...the pipe you can see goes from a pump and back into the fish room

the power outlet for the float switch...this comes already connected...you just plug it in

the float switch...it held in place by a magnet on the inside and outside of the tank...its difficult to get a good picture of it

I did a test run today and it worked a treat

Hey mike is the float switch a stand alone unit? I have only seen them already attached to pumps. Great idea if it is. Where did you get it and how much are they?

Its a stand alone...it comes already wired up...you just plug your own pump into it.

I got it from guppies...was around $30 - $40
