Review: Buy it, It WORKS, from an amateur - I’m new to the fish tank world. I was gifted this 30gal tank, I slowly purchase accessories, decorative item. Got the water tested after 3 week for free at local store. Water became cloudy and dark, because I was constantly moving decor around and removing some fish. These guys are fast and elusive. Anyway, I thought I needed to change out the water. I purchase this ACCU-Clear, I follow the instructions 2ml to every 10gal of water. So, I measure out 6mil. The measuring cap show 5 and 10ml, went a little over 5. Reading the reviews, I was expecting dead fishes in the morning. 1st dose show some improvement after 24hrs. I added 6mil the next day, getting better, 3rd day another 6mil. Now the tank is crystal clear and the fishes are still alive and all over the place. Now, someone offer me a 50gal, I wait until at least 6 months, before I even start to think about upgrading. I would definitely recommend this, go slow and follow instructions, wait 24hrs, before u treat the again. This thing WORKS, for this amateur.
Review: Awesome Aquarium Cleaner! - This is an honest review of API ACCU-CLEAR made for freshwater aquariums that I use in my aquarium weekly. Pros: Accu-Clear is a must-have product for any aquarium owner, as it works wonders in creating water clarity in your aquarium. I use it in mine once per week. Just a simple amount about the size of a nickel can significantly improve water clarity and remove any green coloring. Opportunities: None. This is a great product at a good price point that is also in a supply amount that will last a very long time. Overall, ACCU-CLEAR makes cleaning and maintaining my aquarium a breeze. It is fish safe and a great product for algae control.

### ⭐⭐⭐⭐⭐ Clears Your Tank Up Fast! Ecellent Product!
*by A***E on July 2, 2025*

This product is amazing. It clears your tank up fast. I had to restart my cycled tank from a year ago because everything got sick. So I started a new tank and got a bacteria bloom. It was the worst I have ever gotten. I had to take everything out of the tank for a bit becuase it was making them sick!. Then I put them back in and finally it started to clear. But the water wasn't clearing up fully. I bought this to help. I put in half of the recommened dose for the first day to not overwhelmed my tank. It cleared it up very well. Then the next day the rest of the dose and BOOM my tank is CRYSTAL CLEAR! I foyu're tank isn't clearing I haighly recommed this product. Follow the directions and use it sparingly so you don't kill your tank though. It's a fantsic product! And it came in less than 24 hours!
