Good for you - but you are solidifying what I was saying - you simply dismiss anything that you do not do or use.
Measured growth rates of several Acropora and Montipora species maintained in a tank using the Blu Coral method are around 40cm per year. This link has some information on it: Need quick SPS growth - Marine Aquariums South Africa, and you'll find MANY pictures of aquariums using this method here: Italy's Best! Matured SPS Aquariums. - Reef Central Online Community
I will place some of these pictures here, which compared to your frag tank, I'd say it is no contest.
And these two are the same tank, taken 10 months apart.

Not all of the tanks above use somatotropin, but the common denominator is intense lighting, intense flow, high parameters, great filtration (using the Berlin method), and feeding of ultra-high protein fresh foods (which a lot of breaks down into amino acids, triggering extreme feeding responses from corals to where they will take in far more food than if just fed using 'normal' dry foods).
If you do decide to run your parameters at higher levels, you MUST accompany this with more light and more food or your corals will suffer from it, which is very common among tanks that have excellent filtration and are not being fed accordingly.
I may not have a 'stunning' tank by any means, but I at least do my research and learn the hows and whys for all of this, and I suggest that you do the same.
I'm with you, If people put half as much effort into maintaining their tanks as they did beating their chests & declaring their infallibility on public forums, the world would be inundated with Tank-Of-The-Month quality tanks. I personally run my tank at 10.5 dkh. Not because I particularly want it to be there, but because that's where it stabilized. I think the fact that it is stable is 10 times more important than the fact that it happens to be 10.5. It's also worth noting that I dose .4 mL of a VSV mix on this tank daily (100g system). My fastest acros grow about 1 cm every 16-20 days. I think we all need to try not to let our personal preference for richer or more pastel colors taint this discussion. My personal preference is for richer colors so I keep some gunk in my water, and (most importantly) try to pick acros that happen to look good with saturated colors
! I have seen plenty of pastel tanks that made my heart skip a beat as well, Krystof's is one of them.
