water top off

[falv125]

is there a product or easy way to build an auto-top off system for my tank?

Sounds interesting to me... a system like that would welcomed by lots of us in the marine hobby. Sounds like something that could be crafted from a toilet tank valve system and put in a sump. The feed can come from an installed R/O system. I would imagine that would be easy to do provided running water is near the location of the aquarium and hooked to the R/O system underneath the tank. In my house the aquarium is on a wall that shares with the bathroom. I'd imagine there would be plumbing in there.

This is where I eould start if I had to build my own. I have no clue if this has been created already but thats just my .02 worth.

Most people use a sump that's filled with plain RO water, and a pump in it hooked to a switch like the plunger on a toilet. When the water level drops, the plunger goes down, thus completing the circuit and turning on a small pump in the sump. It pumps the RO water out into the aquarium, and then shuts off once the switch is up to a normal level.

I know there are tons of plans out there on the internet, and a few people on RC might be selling ready-made kits. Just search around for "auto top-off" or "float switch". Here's an easy DIY rig I found just now:

To this I added, from autotopoff.com a float in my display that powers my Mag 7 return pump (can handle up to 1000 watts so a heavy duty relay in there), with a memory switch so if water level goes too high one has to check things out and reset before the pump will go back on, thus sparing the danger of flood over the top.

I am thrilled with this and have had no problems for nearly a year now.
