Welcome to our forum.
ok, but are the concentrations the same?Does 1 Tsp of alk up = 1 tsp of baking soda?I have my water totally dialed in right now and hate to play with it.
It should really come down to if you like your dealer or not. If you bought your tub just because then go where ever but if you bought your tub based on the dealer then that is where you should buy bc who is going to be there in the end when you need them not W-Mart or w/e you support them they take care of you especially when it comes time for maybe a new tub.
