FREESEA First Impressions

Contains 2 bottles.

I have already repurchased and given a few to other people as well. So they fit in my Tetra filter for the fish tank. I don't think the review about not replacing the filters is correct. 5 gallon Top Fin Enchant Aquarium that I got from PetSmart. I have never had one tear or fall apart under any circumstances. I tested it again this morning and it's down to 838ppm. I do not use this as a product to treat my tap water.

FREESEA Final Thoughts

He didn't eat them day 1.

The filters are expensive to replace and only so-so quality. Fish are aerobic organisms that are susceptible to ROS. I'm glad Amazon had these small cartridges. Exactly the same item I purchased from a local store for alot more money! Fish are aerobic organisms that are susceptible to ROS. This is my go to water conditioner and stressed fish treatment. Easy to use and a great price here at Amazon!
