pH Down - 7lbs

Thank you, everything is perfect

Works well with iopool, but pricey

I liked the fact iopool provide the simple and precise measurement to be add to the pool, but the product is pricey. As 8/4/2023, the price is about $5.72 per pound but you can find similar Sodium Bisulfate for $1.60 per pound at Walmart or Amazon.

Expensive

It is expensive and doesn't last very long after lowering the PH.
