This is just IMO, I would never say that my way of doing it is the right way. And I didn't mean to come off saying your doing everything wrong. Also I defiantly agree with water agitation with keeping the water oxygenated
I have a controller, which is the best investment I have ever made, it has a PH probe with it. I have never calibrated it, it has always been around 7.7 I have never worried about it being low the only thing I worry about is keeping it stable it has been probably been 6 months since the last time I checked it. If I see bad polyp extension then I would check it out. My biggest problem over the years has been temperature swings with a controller my temps stay between 77-79 I use LEDS so I need a heater in the winter, which the controller regulates and a fan that comes on at 79, which the controller also regulates.
The older I get the easier and more realistic I try to make things. I am not saying that trying to achieve perfect numbers is a bad thing, but 6 months from know are you really going to want to continue to make parameters perfect, I know that I would get tired of doing so. then your corals would suffer because they are not used to the declining numbers such as Cal and ALK, but would then recover over time to the newer more stable and easier to achieve numbers. Ever hear from people that give up on a tank, but keep the pumps running only to say after a year of doing nothing every thing looks the best it has ever looked. I truly believe that corals will adapt to our aquariums if given the time to do so then it is our job to keep every thing as stable as possible. I do this by allowing IO or reef crystal (or what ever salt mix you us) do all the work by adding the necessary ingredients, thus IMO is the easiest way to maintain by doing a 5 gallon water change every other week.
I am to lazy to achieve perfect numbers, plus I like to travel and I know my tank sitter won't get it right, so I guess I am doing the lazy man to reef keeping. I used to be one of those guys that used to mess around with the tanks chemistry only to end up making things worse. I guess my point to all this is I have an SPS tank that I have never added anything to and it is going pretty good and I think keep it simple approach is the reason why.
