Sorry to ruin your thread. Try not to take this so personal, it is a post, an opinion. You love the AP700, we all can see that

.
I'm trying to follow the topic but obviously you are against it, which is ok too. I've been reefing for many years like many here, and what I mean to say is Led companies claim the units they make (Kessil one of them)can keep corals healthy while covering EFFECTIVELY large portions of a tank, which I do not believe reflect what most out there experience.
My first post on this thread basically says I am a FAN of Kessil however I wish instead of making a larger fixture such as the AP700, claiming to cover 36-48" tanks, they should maybe consider smaller dual cluster units, so we could fit more of them in our tanks having better coverage.
Contrary to your statement of gathering T5's to leds in order to get the "ultimate lighting system" I feel led companies claim and sell their units with the promise their fixtures are already complete systems covering properly without need for other type if lighting. If you read lengthy forums about AP700's you will notice hobbyists buy those fixtures and later add T5s after missing better coverage in their tanks and most of all, noticing shadowing issues, especially at the ends of the tank.
Out of topic, I am hanging 5x Radion G4 Pros over a 60" tank as I feel it will prevent shadowing. The store I go to has the same set up and does look excellent for months now. I do not buy Ecotech's recommendation of 36" of coverage per unit at all. It is not accurate.
The post above asked for users here with mature sps tanks which have had AP700's for over a year as a way to measure how coverage of that fixture equals in a tank after longer time. Do you have such tank to prove this? I'm not jabbing at you just asking for opinions
