I was curious if it is all ice cap ballasts or just halides? I am going to run 2 660's and not sure which controller yet I am in the research stage but soon to buy in the next month maybe. I don't want trouble. does a noise filter do a good job of controlling problems or do I have to use a dc4 or 8. search doesn't work on reefcentral for me so I had to start a new thread in order to find an answer this year there is way too much info to try and sort through here.
thanks a million,
