## Description

Many factors can affect the water in your aquarium – changes in pH can be caused by the breakdown of waste in your tank, or local tap water with low pH or low alkalinity. Maintaining the proper pH level of aquarium water is important to ensure a healthy environment. Tetra® Correct pH® Tablets maintain the recommended pH levels in your aquarium to help reduce stress due to harmful fluctuations. Use Tetra® EasyStrips™ aquarium test strips to determine the pH level of your water and treat as necessary. Add one Tetra Correct pH Tablet to each 10 gallons (40 liters) of aquarium water. To avoid drastic pH changes, check the pH 24 hours after treating before adding more tablets. For aquariums 40 gallons or larger, dissolve the tablets before adding to your aquarium. Treat monthly to help maintain ideal pH levels in your aquarium. Each tablet is pre-measured and ready to use. Contains 8 tablets Since 1951, Tetra has developed the world’s most comprehensive body of fish food knowledge, and fishkeeping enthusiasts have looked to the brand for products and solutions that add ease and beauty to their home. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need–-from a large variety of quality fish food and innovative equipment to test kits and decor.

Review: Correct pH with Ease by Tetra Correct pH Tablets - 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 desertcart's pricing and delivery speed have always been excellent.
Review: I love my fish tank - 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

## Questions & Answers

**Q: Is it safe for invertebrates? Is there any cooper in the formula?**
A: Is not safe for anything all adds high level of phosphates in your aquarium.

**Q: How exactly does this work how will a tablet flip the ph up or down? Or is there tablets for ph up and ph down in this box? Nothing else does both**
A: It works by raising the ph.  If you need to lower ph use driftwood and some moss balls.

**Q: Maybe a dumb question, but if i drop 1 tablet into a 10 gallon tank, is it just going to automatically get the ph to 7ish? cuz my ph is currently low.**
A: I would add a tablet and then test in 12 hours. Maybe add another if it’s low still. You might have too many fish in a 10 gallon if your ph is that low. Could be a lot of other factors too but make sure not to over populate.

**Q: Do you need to remove the filter while applying the tablets?**
A: No, but we do recommend dissolving them outside of the tank in a cup of fish water first.
