If my fish tank is ever not balanced I put this in and the results are immediate. It’s cheap and super effective and if helps keep my fish safe and happy. I’ve been using this product for over a few months now and my fish tank has been perfectly balanced.

Fast shipper. Good communication. Price was good. Good amount. Works well in fish tanks.

I was rather skeptical of the product Correct pH Tablets by Tetra, but after using them, I simply fell in love with them. It is very easy to use- just drop the tablet into a safe place in your aquarium, and it just fizzes away, doing all the work for you. I have a 40-gallon tank, and these balanced out the pH perfectly within less than 24 hours. So impressive, that I've stopped testing my pH level on a routine basis, trusting these tablets to keep my tank in a perfect state.What's even better is that you don't have to use them as often as the instructions suggest. I usually use two tablets a month on my 40 gal tank and it still manages to keep my tank well balanced. The dosage of each is easy enough to adjust, based on your tank size-just break the tablet in half for smaller tanks or add more for larger ones. It's really hassle-free, and my aquarium has never been healthier.I've purchased this product continuously over the last several years and Amazon's pricing and delivery speed have always been excellent.

I think I will stick to the liquid kind in the future, it seems to be a better value, however these work okay.

I check the water in my fish tank regularly. And often I find there is a problem with the Ph. Once I put one tab my water has more clarity. It is very easy to use. Its performance is phenomenal because the appearance of the ph regulates itself. I have bought this product many times for my fish tank. The tabs are a good size and stable. And my fish tanks appearance is wonderful. If you love your fish. You will love this product that stabilizes your fish tank water

Cleans the tank great and for a good price!!!

So I have test strips and I have a 3 gallon betta tank but we have hard water and high ph. Well I started with a half tab and added it … didn’t do anything. Waited two days and added a full tablet well this stuff makes the water beyond cloudy and develops a type of film resembling plastic bags. I did a partial water charge and when doing so I was amazed at the layer of film I saw I’m hoping when I come home from work the filter does its thing and filters some of this film not really a happy camper.

Love these works great

gets the ph to a correct level

ok

Worked well got my ph of 5.2 to go up to 7 in 24 hrs or so and its held for over a week now it does what it says it does

Great product to buy in bulk for ph balance & works at it should

Seems like the sticks read that everything is perfect in my tank, but a couple of my fish died and my Betta doesn’t seem to be doing well even though I’ve done partial water changes as suggested. Not sure if the sticks are accurate or not.
