About

Salt Water Pool Answers exists because of one fact that almost nothing else tells saltwater pool owners: your salt system cannot measure salt.

It measures how easily electricity crosses the water in the cell and infers a salinity number from it. That single detail explains most of the expensive problems in salt pools. It is why three different tests give three different answers. It is why scale, cold water and a wrong menu setting all produce a LOW SALT warning. And it is why so many owners end up paying for wasted salt, a partial drain, and a new cell, in that order.

We found that out the way most people do, which is by reading hundreds of forum threads where owners describe the same problem and get told to buy a better test kit.

What we do here

Three things.

Calculators that handle the cases the others skip. Nearly every free pool salt calculator online will only raise your salt level. Eight of the nine we audited cannot tell you how to lower it, and the largest cell manufacturer publishes no calculator at all, resolving the question with a hand-waved fraction in a blog post. Ours handles both directions, works out what a partial drain does to the rest of your chemistry, and does not pretend your pool volume is a number you already know.

Writing that starts from what owners actually get wrong. Not from a keyword list of topics that sound sensible. Every significant page here traces back to a real thread where a real owner was stuck.

Two paid guides, for people who want the whole diagnostic in one place rather than assembled from twenty articles.

What we are not

We are not a pool store. We sell no salt, no cells, no systems, and we are not affiliated with any equipment manufacturer.

We are not a testing lab either, and we say so on how we test. Trust us on method and arithmetic, and treat our equipment commentary as informed reading rather than bench results.

We are not a pool service. If you would rather pay someone to handle it, that is a perfectly good choice and it costs around $80 to $95 a month for saltwater service.

A note on the scope

This site covers saltwater pools in the United States. US gallons, pounds, Fahrenheit, and US equipment and retail.

We deliberately cut everything non-US from our plans, including the metric guidance and the Australian equipment vocabulary, because half-serving two markets on one page serves neither. If you are in Australia, New Zealand or the UK, the chemistry on this site is still correct but the units and the brand names will not match yours.
