3rd does and no difference.
I've tried this product 3 times according to the instructions on the label and no change at all. I'm using the API master test kit and have no fish in my new tank, so this would be the perfect time to try this product, but I've had no difference at any time and I've tested the water 5 times over 3 days. Going back to RO water to lower the PH which I know does work.
Awesome results! All API products are really good and effective... Thank you:)
Fish need proper PH
Great product. Our feeder fish are now pets. They need balanced PH.
It kinda works
Yes this definitely lowers the ph in my tanks but I went back about 4 hours later to test the ph again and the ph had gone back up to the original levels.
Great for ph upkeep. Works almost instantly. Will be purchasing a larger bottle with my next chewy order.
The applicator I wanted
Drop applicator package is just right for my one gallon Beta bowl. Reasonable price. Good delivery.
Great product for a great price.
Chewy had this product for quite a bit cheaper then our local pet store. I bought it and got it super quick. It does exactly what it says it does.
I couldn't find this product in the 16oz bottles anywhere local and Chewy.com had them I bought 2 and I got them in 2 days. Definetly going to start buying all of our pet needs here.
