Ultimate water conditioner

I have used Ultimate water conditioner from Aquarium Co-Op for many years. It has worked well for me. I have several aquariums and I use it at every water change. My fish are healthy and happy. I trust Aquarium Co-Op products and their very helpful staff.

Ultimate Water Conditioner

This is the best water conditioner I have used. My fish seem happier since we started using it. It has been helpful to use between water cleaning and water changes if they need to be postponed.

I like

Easy to use. Has a slimy feeling, which I guess is for the slime coat. I would buy again.

Great conditioner.

I use this primarily in conjunction with Ich-X when quarantining or treating sick fish. Works great and doesn’t seem to mess with the potency of meds.
