APIPROPER pH 6.5 Freshwater Aquarium Water pH Stabilizer 8.5-Ounce Container

It said not to use if you have plants, so I only use this sparingly. But it definitely works!I was having trouble bringing down the PH with almond leaves and other botanicals.

I was having problems getting the PH down in my aquarium. We use well water and it had a PH upwards near 9. I tried several other things and while it brought it down, it was slow. The PH 6.5 works very well and keeps it stable. I use it every time I do a partial water change. The fish all seem to be happy too.

Works as advertised in aquarium.

It worked for a couple days. My waters just too rough to try to maintain this low of pH.

Interesting the way it says “do not use with live plants” but interestingly, you can use it with live fish..?I have been using this product with ALL of my plants to keep my ph stable at 6.5 with my caridina shrimp. I also keep neocaridinas at this ph. They all thrive very well.I do use RODI water. I add 1-2 tsp with my 7.5 gallon water, which my PPM comes out to 60-80.I grow Subwassertang, flame moss, and among other plants. They do fine.

I tried using this product 3 separate times and after every time when I test the water, the pH doesn't move from where it was to begin with!

Great product works like a charm and stabilizes water PH. I use multiple versions of this product depending upon the aquarium. Only thing I don't like is that they don't make a larger size for volume usage. We have 14 tanks at the moment and will be adding more in the future. on water change day we go through 100+ gallons. @API - Please make a larger size

One of the bottles lids were broken so the powder was all over the inside of the box
