I use the temp probe. I don't use the ph and I nevere really check ph. I use a jbj for ato , I wish I had the vdm to run my jebaos but I ll add that later. I have my halides hooked to it so if temp in the tank gets above 83 it will turn the lights off. My display went out so I do everything from my phone now. I'd like another eb4 or 8 to run my pump and skimmer so I can control them if need be. The list is endless.That's along the lines I was thinking as well. Buy the best I can and not regret missing a piece of equipment later. I just have to settle on which one.
