Fritz Aquatics 83372 FritzZyme 460 Biological Conditioner for Salt Water Aquariums, 32-Ounce

This product worked perfectly to clear up a bacterial bloom in my 65g saltwater tank. Had the bacterial bloom occur overnight and used this recommended product with the listed initial dosage. It started to clear up overnight and after a couple days completely cleared up. Will def use again and recommend for bacterial blooms

Absolutely Fantastic

I didn’t know if it would work. I have a 150 gallon reef tank that has a high bio load. I suck up detrus weekly, do water changes, etc. but still would get a bit of cloudiness from time to time. I tried this and have been amazed at my water quality as well as my phosphate and nitrate levels. Highly recommended.

Killed one salt water fish. Added like they say. Now one more is dying.Changed the water still not helping. Horrible stuff for fish. Cleans the sand, but kills the larger angels

I really love this product. Since I started using it I have noticed that my sump stays much , much cleaner. It took a little while for me to notice any changes but once the stuff started working .. WOW ! I think everybody that has a reef in their home should try it.

When I put in a tank it is lowers nitrat 8ppm to 4ppm after 1 week later

Awesome product! Really does a great job keeping my sump and refugium clean. Noticeable difference in detritus and organic gunk that typically settles in areas of low water movement.

started using June 11th and still don't see any difference today June 19thI will not order this product again
