Good stuff
It does a good, adequately changes pH and does it fast. It's easy to add to the water, just use the measuring cup in the cap. Use a test strip before and after and you should see the difference. I have a large aquatic turtle in a 300 gallon indoor pond and this product couldn't keep up with that long-term. What it did do was give me a safe way to treat the water for pH, temporarily, while I got an appropriate system in place. It's a good price for that kind of snappy resolution. Thank you!

Stabilize your water with this product!
If you are having a plan to properly setup a new big size aquarium or even water change, this is a good recommendation. Our pH was more than 8 when tested with pH aquarium test kit. Would recommend to follow the instructions correctly, particularly not to use too much within a day to stress the fishes. Water clarity is pretty good. Fishes were able to adapt this change & I see them performing healthier. Overall good product for money & easy to use.
