I am using it 24/7 is this a bad thing?
Could this be what is killing off my zoas? All other softies and sps are fine.

what gives? Levels seem to be ok...

I float a bag in the output of the skimmer in the sump..change it every 30 days, that's about as long as it's effectiveness.

I've used it before consistantly and not used it consistantly. Can't tell much of a difference.
 
I used to use it all the time too. 24/7. I changed it about every other week too (sometimes every week).
