I currently have basic equipment for my tank and want to have a way to continually monitor parameters (PH, Temp, whatever). I do not want to be able to control really anything (lights, pumps, etc), but may want in the future. I also don't want to spend a fortune - what are the options I have? Do I really need a "controller" to do "monitoring"? I was really thinking that the SenEye reef has what I am looking for but not sure what else is there.
Any nice summary of 'monitoring' options?
