Taylor Technologies Inc r-0871-e fas-dpd Titrating 16 oz

Does what it’s supposed too and cheaper then the spa shop

Took a while to arrive from the US, but worth the wait and cost to have this reservoir of FAS-DPD titrant on hand. Dropper top of the standard 2oz bottle removes and replaces easily to allow refills from this large bottle.

Arrived as described. Simply refilled my existing small drop container.

Same stuff as the little bottles. If you check your chlorine levels often, like you should, this will last a year and save you money. Just pop the top off the little bottle and use this to refill it. Purchased a few times and the expiration date has always been fine.

Great value, especially when SLAMing. Says it expires after a year, so this much may not be needed for everyone.
