I have a 35 gallon tank. I take, what I consider, very good care of my tank and fish. I do my scheduled water changes and vaccum the gravel whenever I do the change. I have dumped approx 20oz of ph decreaser in the tank with no change in the ph. I even returned to the store to buy another ph tester because I thought mine was N.G. In the past I used the granular, wish worked great. Unforunately I can no longer find granular........

Cons: didn't work

This product is a joke i have a 20 gallon tank and had to decrease my pH so I went out and bought Top fin brand which I never had a problem with until i tried this pH decrease. I used half the bottle with in 48 hours and all it did was make my water cloudy. It did absolutely nothing for my pH levels so i brought it back. I love the top fin brand they usually are cheaper but i will never buy any chemicals from them again all it did was waste my time

I used these products in my fish tanks and found their results to be rather inept. I have a 10 Gallon and a 30 Gallon tank. I have had an aquarium for 5 years. The decreaser did nothing even after I used twice the recommended amount. I would not recommend this product to anyone. It is a waste of time and money. I have found two things that work for almost any problem you may encounter with your aquarium changing 50% of the water in your tank and aquarium salt. I have found these methods work the best for everything. Ammonia, diease, Ph, algae, every possible problem you can imagine.

I was trying to increase the pH of my tank so that it would be more suitable for my mollies. I used Increase pH for about 2 weeks and saw no difference at all in the pH. Some days the pH actually decreased. It did however, increase the alkalinity, which was good. The measuring cap was convenient and made it much easier to get the correct dose.

This product works extremely well and is very easy to use just follow the directions. My fish don't seem to mind it either.
