I agree fully. I have never owned any testing equipment for reef tanks or FW tanks besides the new phophate meter and a refractometer. There are a lot of people that are obsessed with making their params perfect, when in reality, the perfect level is much different for every tank. I learned from people who used intuition, which is a very good thing to know how to use. The downside to this is that when I'm at school, my mom does not have this ability yet.
