1.019-1.020 doesn't do anything to ick. If you have the parasite in your tank then it would still show up.
Fish only can do well in a lower salinity levels, but I have heard they have less color.

I'd like to know what is your salinity level for your fowlr tanks..
35ppt - 37ppt is the appropriate salinity for live rock. If you keep it lower then the animals that inhabit the rock will die off and you'll be left with rock that only has bacteria.
Fish can cope with lower salinity for quite a while but reef fish live longest at natural seawater salinity.

Additionally lower salinity don't make sense, because you'll loose skimming capacity. Keep the levels up...

The 35 - 37ppt is a Salinity range (amount of dissolved minerals in the water). The other range you're thinking of is Specific Gravity (the density of the water). To convert Specific Gravity to a Salinity reading you also need to know the temperature of the water and a conversion chart.

Dear hobbyist,I keep my specific gravity at1.022 - 1.023 ,and my fish appear to be happy .
haha as opposed to...
I keep mine at 1.025 and mine "appear" happy to. They laugh they smile, they all have a good time when the lights go out. I swear one came out and stole my beer last night!!

can you backup what you just said? cause i keep all my tanks 1.020 and my skimmers skim just fine ive had my tanks higher in salinity and my skimmers skimmed the same as at 1.020

Try skimming freshwater
The higher the salinity level, the higher surface tension water has, technically the more air be injected, the more foam can be produced, and more be skimmed out.
As far as your particular situation, who knows.
That particular skimmer could not be affected too much, or is 'over-pumped' already and skims out it's max at lower salinity. Or it really just could be a percentage difference that it really doesn't matter. Though, in theory, maximum skimming efficiency is acheived at full salinity, even if it is a minute amount of difference.

It is my understanding, (and i could be wrong) that skimming has to do with buoyancy, and the lower your salinity the less bouyant stuff in your water is, thus less effective.
Personally I kept my fowlr tank around 1.024 or so. I've seen guys keep fish only tanks at a hypo type level, others a round 1.018 or so, to keep down parasites. But real salt water is closer to what bang guy says. Depending on where you are at. I have no idea if running low is worse for a fish. I do know that the more salt in solution the less o2. So I never was a fan of running the sg as high as bang guy it seemed that my fish were gulping for air when I did that. Although I have absolutely no scientific proof.

As usual, I find myself agreeing with Bang Guy.
The inverts in your live rock need natural sea water salinity.

Hm, Now I have to agree with both of these guys
In all seriousness, keep your salinity at 35-37ppt. It is closest to natural seawater. Most of what we keep thrives more at that level.

interesting cause at 1.020 my liverock is full of life, idk i guess everyone has different thoughts on what works and what doesnt but i can honestly say i sufferd no i'll effects of running 1.020 levels

How can you know? I have no way of knowing about your rock but I would guess that there's less diversity because of the low salinity. There are many species of Copepods, Amphipods, and Isopods that will thrive in hyposalinity but how are your Mysid Shrimp and Cirratulid Worms?

Your rock is obviously functioning well so it's working fine for your tank. My intention isn't to take that away from you. I'm only pointing out that it's possible to lose diversity with hyposalinity. Again, there are many worm species that do fine in hypo and there are many that don't.
