I've been using API products for over a decade and they all do exactly what they advertise when you follow the directions. They also have a great live response team if you have any questions.
I live in the Chicago suburbs and have an 1800 gallon pond. Every year for some unknown reason I get a spike in Ph in the late fall. API Ph down works better than any other product I've ever used to bring it back to where I think it should be. I'm told anything between 7 & 8 is okay for a pond to thrive. Great products at great prices. It just don't get no better!

Rated 5 out of 5 by bumper Wonderful products with out the high cost of buying from a retail store
I have several tanks of fish and some like high PH, the South America cichlids, also parrot fish, so both these products helps me to keep the PH balance and use the buffer to stabilze the PH another wonderful product
