Buying advice

When choosing a clarifier or enzyme, match the product to your pool size, usage pattern, and maintenance style. Clarifiers work quickly to bind particles for filtration, so a good filter system is essential. Enzymes act slower but lessen organic load and filter cleaning, making them ideal for busy pools or spas. Consider budget, eco-preferences, and whether you need a one-time treatment (clarifier) or ongoing protection (enzyme).
