77G Reef Tank first wobbly step

[fkshiu]

Don't bother with a chiller yet.

You can raise the fixture the cheapo way by resting it on a pair of wooden blocks (like 2x4s) sitting on either side of the tank (running front to back).

Then you can use a small clip-on fan blowing across the water surface.

Should work well and be much more economical than a chiller.
