ACCU-CLEAR Water Clarifier for Freshwater Aquariums - Quickly Clears Cloudy Water, Ideal for Weekly Use Review

WOW! I received it at 3pm today and applied it around 4pm. 9pm and the old muddy water is crystal clear now! Wonderful! Plus it doesn't take much at all so it's an amazing price for an amazing product that will last me a long time! Thanks very much!

I originally gave this product five stars. I have since downgraded it to 1 star as it nearly killed my fish last weekend. I followed the instructions as every time I filled up my tank the whole tank turned milky white. I had several fish swimming to her side. I ended up draining 80% of the water and using dressing instead. And all my fish survived.

I have never needed this product, but I encountered a situation where the water was cloudy and decided to try it. As I poured the product into the tank, it immediately became cloudy and eventually cleared. but only to the same transparency of the water before adding the product. I love API products but this is the first one that didn't work as intended.

This product is terrible. I changed the chemical balance in my aquarium and everything was fine. I used less than the allowed amount of this product 4 hours ago and when I came back all 20 of my fish were dead. I would say poisoned. They were perfectly fine as I had them for 6 months. Now I have to replace all 20 expensive dead fish. I want to be compensated for my lost fish.

Used them on my 55 gallon tank as intended. Had one dose and another 24 hours later. The fish were gasping at the top of the tank and my catfish swam almost dead across the tank. I did an emergency water change and was able to save her. It did not affect the clarity of the water in any way and I am convinced it is toxic to the fish. I have used Tetra Water Clarifier in the past and have never had a problem. I have requested a refund for this Revain product.

I've had the tank running for several months now with no problems. I bought API Accu Clear because I wanted crystal clear water in my aquarium. The water has cleared; However, in less than a day, several cardinal tetras "disappeared". I later found them in the substrate - dead. Correlation does not equal causation so I tried Accu Clear again a few weeks later with the same results. I haven't used it since and all my remaining tetras have been fine. I love API products but only buy Accu Clear if

I've been struggling with cloudy water in our small aquarium for two months. It got worse every time I cleaned it, and by the time the filter finally seemed to work, the poor java ferns and moss ball were getting covered in algae. It was a tough cycle. I finally gave in and bought this product. I read the instructions, measured the product and added it to the tank. I saw it work right away, which was pretty wild. In less than an hour the tank was completely cleaned (see photo!). It's been 4…

We used this product as directed to purify the water in our 55 gallon aquarium. I have used the product before with no problems. but this time (brand new bottle) something was obviously wrong with the chemistry and it killed my entire armored catfish population overnight. Before bed they seemed normal and when we woke up the next morning they were all dead otherwise I would have tried a water change to make a difference. All but one of my Coreys were albinos and some of them lived with us for…

I struggled with white cloudy water and green algae blooms for months, nothing helped. I changed the water every day, vacuumed and did whatever was necessary to maintain the aquarium. I've read some pretty scary reviews about people blaming this product for the deaths of their fish and whatnot. I remember a review where someone accused this product of killing all their brown catfish. All I can say to these negative reviewers is buy it, put it in your eyes and learn to follow the directions…
