i wouldnt disagree that testing is not needed, because it truly isnt. however, you also dont have to change the oil in your vehicle. testing water parameters is simply so that you know where you are with things. thats it. testing your water doesnt do anything for your tank. it only tells you if there is something you should think about doing.
with that said, the OP is using very frequent water changes in place of parameter testing. if water changes are done often, then the parameters should be about equal to what the salt mix equates to. thats assuming that the contents of the salt dont settle, but with frequent water changes, they are just blowing through water like no tomorrow, so ya. no water testing is really needed in this instance. but, with that, the assumption is made that the salt mix has the ingredients needed to replenish. its a gamble i think i would be safe with, it im certain about that salt mix enough.
i would not call this an established reef tank tho ( i wouldnt call it a new reef tank. i would say its the fairly new reef tank. its not even a year old), nor would i say your fish are as big as they are going to get, as claimed within this thread. the pictures that do show the fish, those fish are maybe half size of what they can get to. a gramma can get surprisingly large, as well as clowns. ive also seen a tail spot be considerably larger than the one you have.
you also claimed that you dont test salinity or temp. i believe i read that you get saltwater from somewhere, so i assume they control the salinity, but that looks to be digital temp in the background of the tank on the left. so, to be fair, there is at least that.
