How many of you use chillers for your reef tanks?

If you are not choosy, can consider all the 2nd hand chillers being released by fellow reefers. one CL-300 was going for $40 recently.

now adays chiller is a must for a reef tank cause u can see a tank with two pump can cause it to arise to bout 29 without light with light it can go up to 31.++

Another good alternative is having an external pump instead of an interal pump to recuce the heat being transmitted into the water hopefully making the chiller work less harder..
