For me testing daily, specifically Alk, was what got me to the point of really learning my reefs consumption on a daily basis after getting into the SPS world ! I like gadgets and new technologies but have also learned that a saltwater environment, breaks or eats up everything. I speak from over 28 years of living off the ocean commercial fishing yellowtail snapper, and always having to repair or replace something on my boat that the saltwater environment consumed. Don’t take this in the wrong way, I think that it’s great that people have invented such great gadgets and it helps many people enjoy their reefs at home without having to stress about leaving because of work, or cannot attend to testing because of their hectic life, trust me that I understand. I just have gotten to the point and learned it the hard way to go by the KISS method, the older I get, the simpler I make things for myself, so that there’s less things that I have to worry about, “And that’s all that I have to say about That “ .
