API pH DOWN Freshwater Aquarium Water pH Reducing Solution 4-Ounce Bottle

Most fish don't do well with super high ph water like we have here in Eastern Washington. I put a capful in every bucket when I refill the water to keep the PH down at a more neutral level for my tropical fish. Works well.

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.

Seems to work and the fish are not affected

Honestly idk why it was recommended to use this it works like magic but damn it's toxic spilled some on shirt and it discolored it like bleach thinking at this point windex would do bout the same thing except it's toxic also can cause your skin to have a burn sensation so use gloves hope it's actually plant and animal safe

Great price as compared in pet store. Thank you.

worked well to balance ph levels

Adjusts aquarium PH as advertised.

I was so excited to receive this so I could stop worrying about the high PH in both of my fish tanks until my almond leaves came in. It worked very well for my 5 Gallon tank but sadly, it made no difference in my 20 gallon :( i listened to the instructions, I’ve done more frequent water changes, I’ve put more than the recommended amount (there’s no fish inside!) and nothing has been working :( guess I just have to keep waiting for my almond leaves!
