Affiliate disclosure

What we participate in

Pool Water Guide is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate we earn from qualifying purchases. Our Associates tracking ID is poolus-20.

Product links on this site are tagged with that ID. If you click one and buy something, Amazon pays us a small percentage of the sale. The price you pay is exactly the same as it would be if you had gone to Amazon directly — the commission comes out of Amazon’s margin, not out of your pocket.

Amazon’s affiliate cookie lasts 24 hours. That means if you click one of our links and then buy something entirely unrelated within a day, we may still earn a commission on it. We think you should know that, because most sites don’t say it.

What it does not change

It does not change what we recommend. The clearest evidence we can offer is structural rather than a promise: on our test-kit page the cheapest product wins two of the six possible answers, and the recommendation is produced by a rule you can inspect rather than by us picking a winner. A page optimised for commission would not do that.

We also routinely send people away. Where a question needs multi-season, hands-on comparison that we have not done, we point at TroubleFreePool’s forum, which sells nothing and pays us nothing. And we tell readers when a cheaper option or no purchase at all is the right answer — our cyanuric acid page opens by explaining when not to buy anything.

What we do not do

No paid placements. No brand has paid to appear here, and no brand has been shown any of our content before publication. We have no sponsorship arrangements, no gifted products, and no relationships with any manufacturer mentioned on this site.

No fabricated testing. We do not claim to test products in the field, because we do not. Where you see a product recommended here, it was selected on published specifications, verified buyer review data, and what the product physically measures or delivers. Our methodology is stated on every buying guide, including its limits.

No invented reviewers. Everything here is written under the site’s own name. We have not created a fictional expert persona to make the advice feel more authoritative, which is a common practice in this niche and one we think readers deserve to be protected from.

Prices and availability

Prices shown on this site are a dated snapshot, not a live feed, and they change without us knowing. Always check the current price on Amazon before buying — the figure on the product page is the only one that is binding. The same applies to availability, ratings and review counts, all of which carry the date we captured them.

Questions

If something here looks like it was influenced by commission, tell us — see contact. We would rather correct a page than defend one.
