Why your gallons matter
Every chemical dose is sized from your water volume, so the gallons figure is the one number to get right before you balance the water. Open any model above for the exact doses for its volume, or take the number to the dosing calculator. Capacities are the maker's stated figures; confirm against your own manual when precision matters.
