auto top-off recommendations?

[artarmon42]

Anyone recommend a good auto top off system?

Was looking at the JBJ ATO, but haven't found any reviews (good or bad).

What do you use?

I just recently bought the aqua medic sp 3000(i heard they work really good). Its going to be on my 30g cube sps tank..check out the diary in the sps keepers forum and see how it goes.

50 gallon RODI water storage tank feeds Nilsen Reactor; Reactor (higher than sump) feeds standard medical IV drip. Evap rate about 2.5 to 3 gal./day.

if your broke use what I got,although its a pain in the a s s to set the right drip.

I bought it for 4 bucks at the grocery store(they sell ro water)

Elevated RO/DI storage tank, gravity fill through Kent float valve in the return compartment of the sump. This setup has the minimum number of moving parts.

I just hooked up a reef fanatic level controller on my 90 and works wonderful.

Easy to setup and use.
