    The BEST I've ever used!!
  

*by T***Y on Reviewed in the United States on May 2, 2023*

THE PICTURES TELL THE TRUTH! A difference in just 4 days from the worst to the best!I enjoy a 75 gallon fresh water fishtank and in it live 10 black skirt tetra, 2 pink gourami kissing fish, a 16" Pleco (algae eater), 4 beautiful angel fish, & 10 Corey catfish. My tank was ALWAYS clear and beautiful until my son brought home a little feeder goldfish he won at the fair 18 months ago. That goldfish grew so fast and so big that I started having a major issue keeping my ammonia, ph levels, and nitrite levels balanced! That half inch feeder goldfish grew within months to be 16 inches!! My tank got so cloudy I couldn't see my fish and the ammonia levels got so high once that I killed my beautiful Angelfish and gave the goldfish such horrible chemical burns from it that you can still see the scars on it today! - that I cried! For weeks I tried everything I could to level everything out in my water to the point I thought of killing the goldfish I felt was causing my issues - until I found NUTRAFIN CYCLE. Within 24 hours my water chemical level evened out!! And I haven't had an issue since with my freshwater chemical levels being unsafe for my fish. That was 5 months ago. Since then I started using NUTRAFIN WASTE CONTROL along with the NUTRAFIN CYCLE and my fish are healthy and happy. With water changes and the help of a water clarifier called KLOUDAWAY made by Aquatic Experts (I buy it all on Amazon), My tank has been crystal clear and my tank healthy!!! This stuff works and works fast! It will help just about any tank and keep it great as long as you follow the directions. I'll NEVER use anything else but NUTRAFIN for my tanks! Just look at the pictures. Seriously, my tank got horrible fast - not just looking bad but it SMELLED like a fish market in my living room! Today my tank is balanced and clear, peaceful and beautiful! 5++ stars all the way around!!!

    Works like a charm!
  

*by A***R on Reviewed in the United States on July 29, 2021*

After having a lot of issues cycling my tank I decided to try this product. It only took six days to cycle my tank! I have two other tanks and they took much longer to cycle. I strongly recommend using it along with Dr. Tim's ammonia chloride solution for a speedier cycling. I'm just so excited to have tried this product and will for sure use it again should I decide to cycle another tank.

    Bottled bacteria DOES work, including this product.....
  

*by C***. on Reviewed in the United States on September 9, 2014*

Usually use SafeStart but tried Cycle this time.  There is no doubt that some bottled bacteria do speed up tank cycling. Nay sayers just did not use it correctly.  Cycle's bacteria started munching on fish poop immediately.  I never had above .5ppm ammonia (1day only)  and then lowered to 0ppm within 10 days.  Yes there were 7 gluttonous and pooping fish in the tank who stayed well and unstressed.  I've had fish tanks in my home  for almost 50 years and have always cycled with fish. IMHO It's not cruel, at least when I do it, and my fish flourish during a cycle if you pay close attention, know what you're doing and don't get lazy about daily tank care.  Too many self-centered kids these days want things they have no business having---think of any poor caged or tanked creature who suffers at the hands of these dopey kids or adults for that matter.  Pure abuse.  Use bottled bacteria, it works.  It really does.  Forget what other know-nothing's  say.
