Acid Rain?
The koi pond Ph level is maintains a healthy balance until it rains here on the Oregon Coast. The water turns completely acidic after 2 days of rain. Our drinking water is very acidic too. Update: I made this review and then ordered two bottles. One of two bottles was open. The liquid product was caked/dried on both bottles. Funny how there was no product on the packaging paper surrounding the bottles. Its apprears as if the bottle was open and damaged before packaging.

If you check your fish tank PH and need to fix it, try this product!
I use this in my 55 gallon freshwater tank after doing a water change and while monitoring water condition during the month. Takes a while and several doses to bring PH up to recommended levels, follow the instructions carefully and don't over-add at one time. Product works well if you follow the instructions and are patient. Add and then check tank water 24 hours later to allow to mix/stabilize.

This stuff really works!
I've been using API for a while so I thought I would try this and ...dang! I used the same amount as the API and it took my PH off the charts! This seems to be at least twice as strong as the API stuff.

API is a good company and I'm using their test kit
Jury still out on this. API is a good company and I'm using their test kit. But I have a 300 gallon fish tank with a 100 gallon sump tank and it hasn't raised my pH more than .3 using the entire bottle over 2 weeks.

Comme c'est tout ce que j'ai trouvé sans danger pour mes plantes, le rapport qualité prix n'est pas comparable ...

Im not sure what to say the lid was loose and seal completely off inside the lid. So I don't if product was used and sent back. On top of that it also leaked out in the box, as you can see in the pic.
