"I was very surprised."

If you're treating injured fins or introducing new fish, this is for you. When they disinfect a repair site, they are normally only using chlorine. I've using this for my betta for several years with every water change. However if you want a stress coat, this is perfect. I hope I made the right decision, Betty is our family pet and is really loved! I was sort of nervous buy this product and trying it out. Don't know if that made a difference but it didn't hurt.

Penn-Plax PBC3M Final Thoughts

"It will last a long time!"

Fish seem healthy and active during use. My tap water is very heavy and this water conditioner does it's magic. However if you want a stress coat, this is perfect. Sure enough they are back to their healthy coloration and didn't end up dying on me. I use in a freshwater aquarium and works well. Crystal clear after changing water and adding this to my 2. By the following morning, the water was clear of algae.

"A MUST BUY!"

Use a heater and crank it to 82 degrees again without fish in the tank. It is just as good when compared to other brands of conditioner. Dealing with biological cloudiness in my tank for some time.

"Mostly for betta's."

My water is crystal clear again, and it smells like a healthy fish tank again. I recieved it today at 3pm and applied it around 4pm. Boy, I thought I was having trouble with my filter. It only requires 3 drops per gallon you add to your tank. Crystal clear after changing water and adding this to my 2. You have to understand when to use this product, and what is is used for. This product is exactly what it says it is.

"Of course."

Fish possess an antioxidant defense system to reduce the negative effects of ROS. I know you are going to want to add more chemicals, etc. DON'T just wait everything will be fine. I even poured in extra to help with the healing. I was sort of nervous buy this product and trying it out. I do not use this as a product to treat my tap water. This is the 5th since I put in the product and my tank is crystal clear.

"But that wasn't the case!"

I have been battling cloudy water in our small aquarium for two months. I tried it without the water change and really didn't make a difference. My water is crystal clear again, and it smells like a healthy fish tank again. No exaggeration-- literally cleared overnight. The afternoon I received this product I added half a dose to each aquarium. I love it when a product does what its supposed to. I have used this consistently since cycling my small sized fresh-water tank.
