Clear water
By Jimmy on Mar 14, 2020
I set up a 75 gallon freshwater tank a few weeks ago. I believe it cycled ok but still had a haze for a while. I did everything with the tank I was supposed to do. Water changes etc. I read about the api bio-chem sorb online and decided to try it. I replaced my carbon in both everclear 70’s with the bio-chem zorb. After a few days the water cleared. So far so good.

Pets that don't have legs

Excellent item! After receiving all of my supplies I was successful with cleaning, changing and resetting up my 200 gallon aquarium ALL BY MYSELF. During the previous 4 years since my husband passed away, I'd had someone else do the job.
