Questions We Get a Lot

Still stuck? Our team answers by email within one business day.

Are these genuine BioGuard and SpaGuard products?

Yes. Every product ships sealed from the manufacturer with current lot codes and expiry dates. We do not sell repackaged or relabelled chemicals.

How fast will my order arrive?

Orders placed before 2pm on a business day ship the same day. Most deliveries land in three to five business days.

Which chlorine should I use, tablets or granular?

Tablets dissolve slowly and hold a steady level week to week, so they suit routine care. Granular works fast and is what you reach for after heavy rain, a party, or an algae bloom. Most pools run tablets as the base and keep granular on hand.

Can I ship pool chemicals by air or overseas?

Most sanitizers and shock are classed as oxidisers, so they travel by ground only and cannot go by air. Restrictions show at checkout once you enter your address.

What if I ordered the wrong product?

Unopened products can be returned within 30 days. Chemicals cannot be returned once the seal is broken, for safety reasons. Message us before you open anything you are unsure about and we will help you work out what you actually need.
