Whats the best/cheapest way to raise and maintain a slightly higher GH?

The use of Epsom Salt (MgSO4) and Calcium (CaSO4 or CaCL2) at a
Ca:Mg ratio of 3:1 or 4:1 is good for starters.
1) Epson Salt can be found at your local Pharmacy, Walmart, Supermarket... etc for cheap, no need to get this from any online vendor and pay more in shipping.
2) CaSO4 can be bought form either Orlando, Rex, Greg Watson or whomever else that has it for the best price.
3) CaCl2 too can be had from any of the above but it can also be found in your local pool supply store known as Calcium hardness increaser (Brilliance is one such brand).
4) GH Boosters/Equillibrium can be used as well but if you currently do not have Potasium deficiencies then I would say not to use it as
K increases TDS quite a bit. Not saying it will cause any issues with your shrimp but if you're big on water quality and maintaining low TDS, then why add if you don't need it
