Review on Fritz pH Higher: Optimal Solution for Fresh and Salt Water Aquariums by Sherri Evans

I have 6 tanks and every tank I use has had problems, I have lost about half my fish, they are ending Down in a corner, they look like their skin will be ripped off before they use it. I lost maybe 10 fish in a year and now it's more than half. It killed all my suckers in every tank, this is the only product I have changed. And it hurts to change the water - that's all that stops him. I do a half water change once a week and a quarter times a week and it has worked well. I woke up from my dream only to find my fish were covered in white goo and half of them were dead.
