1.026 good medium considering the corals I have and where they come from.

Using a hydrometer odds are pretty likely that you are really around .020. They generall(not ALWAYS), but generally read high.

I keep it from 1.025-1.026. It starts at 1.026 and goes down to 1.025 due to skimming, then I top-off with SW to bring it back to 1.026.

Funny you should say that...because I actually have 2 meters. 1 reads at 1.024 (instant Ocean - brand new), the other is at about 1.021 (I think it is Sea-Chem). I figure, I am somewhere in between. I hope the old one is not high because if it is then the new one is really high.

with a hydrometer I was setting to 1.025, purchased a refractometer after I was getting some brown out, it said I was at 1.030, slowly fixed water issue back to 1.025 and the colors are now slowly coming back. For the price of a refactometer, its just not worth NOT having one. Especially the higher quality ones that run 50 bucks, worth every penny.

you are wrong. 
this was wildly popular in the late 80's early 90's. it seems it still has not gone away. 
this is incorrect. this all started with using lower salinities to kill parasites that could be living on the fish. the thinking was that if the fish were to be put into a system with a much lower salinity the parasites would not be able to live. the problem with this thinking is the fact that fish should be acclimated, so when you acclimate the fish you are acclimating the parasites also.
fish can handle a huge range in salinity. this is why FW dips are used for removing parasites. the fish can handle it, but the parasites hopefully will not.
it is also cheaper to run a SW tank at a lower salinity, so people running FOWLR tanks would run them lower to save money on salt.
i find it is just better to a salinity that matches as close to NSW as possible.
HTH,

Its "said" that fish tend to get ick and other bacterial problems with higher salinity. My cleaners love bacteria!
