Tetra Correct pH Tablets 8 Count, For aquarium Water

Work great

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.

Have purchased more expensive brands to compare. Tetra is just as good as brands twice the cost. The water quality is easy to test, keeps tank clean and at proper ph levels

These tablets worked astonishingly well. The tablets dissolved quickly and fixed my pH within 1 to 2 hours!My water is very basic, probably an 8.2 or so but these tablets fixed that. I believe one of these tablets worked better than the API pH down drops. See my image for a before and after (1-2hours) pH water test.**I used 1 tablet on a 10 gallon tank. It would probably be a good idea to introduce the tablet by halves or even fourths to slow the stressful and fast pH change in order to give the fish time to adjust.***Updated 01/10/2017: So I found that although these tablets work well they do not resist a 'pH bounce-back.' I checked my water in the morning and the pH had hardly changed from the pH in the left side of the picture I uploaded. These tablets do not work well if you water has a high buffering capacity.

Good 👍

This worked so much better than trying to use ph lower and raisers to stabilize my small tanks Ph. I break it into smaller pieces to make sure it’s not too drastic on the fish.

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.

Great value for the money compared to other stores
