Without going the Neptune route as we do not have a sump, is there another way to monitor levels in a reef tank without the handheld tests? I feel by the time I add up all the hanna, saltfert, redsea testers I would use daily with reagents I could put the money towards an automated tester and just look at a screen. What are some good testers out there that would do this where I could track on a PC then move the system over to a 120 sumpped tank when we get it?
