timers
 

i have the mechanical ones also for my other tank, but i bought ones from king eds for the metal halide and those ones suck. thats the second one and now i'm stuck. I don't know how many watts the mechanical ones are but the metal halide i have with the atinics total up to 760 watts. i also read up on coralife times and alot of people are saying they have had problems.

I had the same problem when I changed my halides from 175W to 250W. I spoke to someone at Coralife and they said it was because of the higher wattage that caused the problem. I had no problems with the mechanical Coralife timer when I was just running the 175W. I got the digital ones from Coralife and so far no problems with the 250W. HTH

Before I bought my controller I always used the mechanical ones. I tried the digital ones once in the past but found that they "lost" time over a period.
