Hi Bob: I have a Artica 1/5 hp hooked up to my 180, Their
recomendations and seems to be working great. Has a built in Thermostat
that holds it within 2 Deg. Not noisey but I have it plumbed tru the wall
to the Garage. So far I am happy with it and I don't have to run my house
AC so low to keep the temp down.

I'm starting to look into buying one. Have a 210 reef tank. Also has
anyone
tried using them with an aquacontroller instead of the built in
thermostat? I'd
like to really notch in a stable temperature.

Thanks;

Bob
