alright so im thinking of getting a reefkeeper lite. i have a few questions about this. can i hook my jbj ato to it or do i just leave it seperate? also i want to be able to monitor my ph so would this do it or would i be better off getting something like a pinpoint ph monitor?im am getting ready to get my tek 4 bulb t5 fixture so im guessing i can run my lights on the rkl. do i really need the rkl?
