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.

Works Great
Been waiting for my new 5 gallon tank to cycle and clear for 2 weeks. Added 1ml and was crystal clear in 2 hours. Incredible

Nice
Works well but it can be difficult to get the right amount because the measurements in the cap are very hard to see.

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.

Extremely effective!
The bloom was pretty bad in my aquarium. I am a new aquarium owner and I didn't know what was happening. Worried about my fish, I asked Gemini about it. It explained the bacterial bloom and even recommended this product. After reading the reviews I ordered it for overnight delivery. It took several doses over several days, but it cleared up the problem. I also moved to a forever filter system and I think that helped as well. I highly recommend this product.

Clears Your Tank Up Fast! Ecellent Product!
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!

Avant sur un aquarium de 800l, les espaces de nettoyages étaient de 15 jours voir 3 semaines maxi, depuis que j'ai découvert cet article, mes nettoyages sont aujourd'hui espacés d'un mois et l'eau est toujours limpide pendant toute cette période. Aucun problème sur les poissons et les plantes

The first 2 days after putting it in our 35 hex, it was cloudy as heck. But then we woke up to the clearest tank ever. I changed the filter, which was new when we put in the clarifier, and it was filthy! I guess it did a great job!

Ottimo prodotto, l'ho utilizzato in un nano acquario e dopo 24 ore, l'acqua è diventata cristallina, peccato soltanto che trovare prodotti dell'API in Italia sia molto difficoltoso.
