Product details

Taylor R-0005-A is the acid demand reagent, supplied in a .75 oz dropper bottle. It is the refill for the acid demand test in Taylor pool and spa test kits.

What the test tells you

A pH reading says where the water is. It does not say how much acid it will take to get where you want, because that depends on how strongly the water resists the change. The acid demand test answers the second question, so you can add the right amount once rather than chasing pH down in steps and overshooting.

Keeping results honest

Reagents do not last forever. Taylor advises replacing them about once a year, and a kit giving readings that no longer match the pool is usually running on tired reagent rather than a broken pool.

What you get

The single reagent bottle only, for topping up a kit you already own.

Questions and answers

What people ask about this product, answered by our pool techs.

What is an acid demand test for?
It measures how much acid the water needs to move pH down to target. Knowing the demand means you dose once and land close, instead of adding acid and retesting repeatedly.
Is this a whole test kit?
No. It is the acid demand reagent alone, a .75 oz dropper bottle sold as a refill for a Taylor kit you already have.
How often should reagents be replaced?
Taylor advises replacing reagents roughly every year. Old reagent is the usual reason a kit starts giving readings that do not match the pool.
Is it the genuine Taylor reagent?
Yes. It is Taylor R-0005-A, the same bottle supplied in their kits.
