Review: Excellent product - Wow!! Super impressed!!! Water is amazingly clear!!!! I thought this would be a scam but it actually works and works well!!! It did not kill any of my fish either. Highly recommend!
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.

*by M***S on February 17, 2026*

Of all the products on the market, Accu-Clear never ceases to amaze me! My tank water was cloudy from sand and had a brown tint from tannins. I used filter floss and did a few water changes but it still seemed like it could be better. This bottle was delivered overnight so I added some before I left for work and by the time I got back home the water was crystal clear! Wonderful work, API!
