Bought API pH UP two weeks ago because I lost two fish suddenly and within days I noticed a huge change in their behavior and the pH levels elevated!

It safely rises my pH levels without stressing the fish. My tank dropped very low after the new canister filter and this got me to where I needed. I recommend getting pH down in case you raise it to high but don't do it the same day wait 24 hours for adjustments to be made.

It did the job it said it will do and I love it must use if struggle with low ph and there prices are lower then everywhere else
We have a 220 gallon fish tank and this product works great in helping us mentain a healthy environment for our fish!
Used this in my freshwater tank. My well water is naturally on the acidic side. Works great!
Love this stuff it's the only way I can keep my shrimp alive and works fast and last awhile before I have to add more highly recommend and cheap as well
I have several small planted tanks that I test monthly. Sometimes the ph levels are a little off and this helps me get it back on track fast. My fish and plants stay healthy and beautiful. I like the small size so the chemical stays fresh, I don’t need too much so the bottle last.
I bought this a couple weeks ago. My aquarium ph was low and this product did the trick.
it raised my ph but my fish didn't love it, even when using less than the recommended dose they were sluggish for a bit. i would recommend a more natural option ( crushed coral has worked for me in the past) for gradually changing your ph
