I got this sample and used it to do a water change in my betta's tank. Worked great, he's happy and healthy.

Pros: Makes water safe

Cons: none

This is a dependable product to make sure the water is conditioned when refilling the tank. Seems to keep the Gouramis happy.

Pros: Easy to use.

Cons: none

I used this on my fish and It really didn't help with their wounds that much from what I saw and by wounds I mean part of the tail was bitten off so yeah.

Pros: simple

Cons: not that effective

I used to use this stuff all the time when we had fish. It works good.

Pros: Works well

Cons: none

I just used the sample I received and was very happy with it. This company doesn't skimp on its samples either. They're all full-sized products. I also received the algae remover pad which worked very well and they included a fish care chart with everything. This was very helpful when the tank developed an algae bloom problem after I'd scraped down the glass.

Pros: Great product

Cons: none
