Big difference! Shopping for a water softener. I take it
a 32,000 grain figure is total resin capacity. That 25 grain
figure is given by WaterBoss for their 550.
How do I compare? Dan

The 25 number from Water Boss refers to the maximum grains of hardness
per gallon that the 550 will handle. You are correct about the 32000
number being resin capacity or total grains of hardness the resin can
soften bfore needing a recharge.
