Standard package size in Canada, UK, and Australia.
Safe Dissolving Advisory: Pour the salt bags directly along the deep end perimeter of your pool. Turn on your primary filter pump and brush the salt heaps until they are completely dissolved. Maintain circulating currents and keep your salt cell chlorinator turned off for 24 hours while the salt disperses to avoid low/high voltage spikes.
Prevent liner staining and cell scale by using fast-dissolving, high-purity pool-grade evaporated salt.
30,000 Gallon Pool Dosage Guidelines & Staging
• From 0 PPM: 801 lbs (20 bags of 40-lb salt)
• From 1,500 PPM: 425 lbs (10.6 bags of 40-lb salt)
• From 2,500 PPM: 175 lbs (4.4 bags of 40-lb salt)
Staging Heavy Salt Additions Safely
When adding 15–20 bags of salt to a 30k pool, add half the bags on day one, brush and circulate for 12 hours, then add the remainder on day two. This prevents localized hyper-saline pockets and heavy floor deposits.
