Product details

Taylor R-0011L-A is the calcium indicator liquid, supplied in the standard .75 oz dropper bottle. It is the genuine Taylor reagent, the same one packed with their test kits.

What it is for

The indicator is what gives the calcium test its color change, the signal you titrate against to read hardness. Used with the matching buffer and titrant, it produces the calcium hardness number that decides whether your water is going to scale up a heater or eat at plaster.

Keep it fresh

Taylor recommends replacing reagents every year. Reagents age whether the bottle is full or not, and an old indicator gives a soft or late color change that reads as a hardness number you can be quite confident about and quite wrong about. Dating the bottle when you open it makes that easy to keep track of.

Questions and answers

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

What size is the bottle?
.75 oz, supplied as a dropper bottle.
Which test does this reagent belong to?
It is the calcium indicator, used in the calcium hardness test in a Taylor kit.
How often should reagents be replaced?
Taylor recommends replacing reagents every year. Old reagent is the most common reason a test result stops matching reality.
Why does calcium hardness matter?
It is one of the numbers that decides whether your water scales or etches. Getting it wrong is expensive on plaster and on heater exchangers, which is why it is worth testing with reagent you can trust.
