Auto-Top-off

[bnhreef]

Hi everyone,

I'm looking to build or buy a Auto-top-off for my 55Gal reef.

These are the specs:

-The main tank has no Sump
-floats or level sensors need to be placed in the main tank
-Not too bulky
-would power a small powerhead that is placed in either a bucket or rubbermaid container.

Does anyone have a solution forsale or plans to make one?

Thanks
