Best bang for my buck

I have very harsh polluted water where I live and most people really struggle to keep fish alive. I completely attribute my success in fish keeping to this product and aquarium salt. I am so glad I stumbled across this product thanks to Cory's YouTube videos! It saved my guppies and made it to where I can now keep a larger variety of fish including tetras and corydora.

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.

I love using this stuff and so do my fish. They get so excited every time I do a water change and use it.

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.

Impressed

Pretty impressed with this stuff. Used mainly Prime throughout my aquarium journey, wanted to give something else a try. So far seems to work wonderfully.

Good stuff!

I've tried most of the conditioners out there. They all work. I like that this one because of the aloe that helps to boost the fish slime coats.

Water conditioner

I noticed my fish were flashing ( just before I spotted ick) I added this to my water change just before starting protocol for ick. Nice consistency. I prefer this to the API which I was using because I saw the fish reduced flashing right away. Hopefully reducing stress.
