I love, love, love this product! Every since I've started using Dr. TIM'S products my Master test readings has been perfect! My ammonia is 0, ph is 7.0, nitrates and nitrite readings are perfect! I've been trying to establish a good biological bacteria filter since April and following Dr Tim's chart is all that I needed. I'm going to paste this on my other reviews, but I guarantee that if everyone follows the regimen that's appropriate for your aquarium you will see great results. I was losing fish as fast as I could blink, and now my fish are vibrant and healthy.
