About a month ago I found out I have incredibly soft tap water (1gh, 1kh) since then I have been using a mixture of calcium sulfate (CaSo4, 2H20) and magnesium sulfate (Epson salt, mgSO4, 7h20) until I get my water change water to about 5-7gh.

Since I have done this my shrimp have been quite prolific breeders and all seem to be doing well.

However, my question was is there any downsides to using these 2 dry salts? I also occasionally add a small amount of gh/kh+ salty shrimp

Edit: These are neocaradinas

At least I can grow Algae

As far as I know (and I really don't), you want to use about 2/3 calcium sulfate to 1/3 magnesium sulfate if you want to make your own... but it would be easier to use a pre-made mix for shrimp. These can include other ingredients in them that could be beneficial to shrimp that they aren't getting from the home-made mix.

I would quit with just occasional use of SS, work out a formula of SS+Ca+Mg and stick with it consistently. As Zoid pointed out SS has other things in it that need to be kept consistent as well.

17.88% Calcium
6.76% Magnesium
2.11% Potassium
0.69% Hydrogen Carbonate
41.50% Chloride
16.91% Sulfate
0.35492% Trace Elements

Sounds good, what would be a good mix to start w in a 5g bucket with such soft water?
