2 part dosing help

[bkelly]

How much Sodium Bicarbonate do you guys mix in a 1 gallon jug - ive got the Randy Holmes 2 part paper saying 2 1/4 cups in 1 gallon for recipe #1 and then a direction sheet from Ocean Aquatics saying 1 1/8 cups per gallon. I did as Randy said but can not get it to dissolve so i wonder if im over saturated. What amounts do you guys add for Alkalinity?

think i figured it out, the recipe # 1 is for sodium ash and you add 2 cups the recipe #2 is for NaCO3 and you add 1 1/8 cups,, i must have over added because i got sodium bicarbonate but mixed as for sodium ash. thats why it didnt fully dissolve.
