Review on 🐠 Fritz Aquatics Fritz pH Higher: Ideal for both Fresh and Salt Water Aquariums by Theresa Grieve

The product is highly diluted and has almost no beneficial effect on pH in water. Follow Fritz's instructions for the higher pH bottle (e.g. shake before use, 1 cap/20 gallons, etc.). Within a few weeks, I noticed that the pH of the aquarium was getting more and more acidic. Bought a second pH test kit to make sure it reads correctly. Withdrawn a sample (4 oz) from an aquarium tested at pH 6.2, added a full capful of 'Fritz pH high' to this 4 oz sample, waited 10 minutes as directed and retested the sample. The pH showed 6.4. Did the same test with another pH up product in a 4 ounce aquarium water sample and the pH peaked at 14+ - as it should be.
