API ACCU-CLEAR Freshwater Aquarium Water Clarifier 4-Ounce Bottle

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!

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.

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!

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

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

Overall the product does as it is supposed to do, This is my first ever review that I thought I needed to write because it made such a huge impact on my tank. First I would like to say no matter how lazy you are please always wash your substrate. I got about a lil over 30lbs of Seachem Black Sand Substrate in this new set up in order to keep my root feeding plants happy. I do have a couple of Kuhli loaches so the substrate was a plus as it wont scratch up their bodies and they can burrow when they want to. I made the mistake of not washing the substrate thinking I can just pour the water through a strainer so it wont disrupt the dust as much. Boy was I wrong, sure enough you can see the plumes of dust just circling around the tank as shown in the picture. I was skeptical about this product since people were saying it killed their fish thankfully I didn’t have any fish in there while I added this product so I cant tell you if it is toxic to your fish or not. However keep in mind we never truly have a full tank so under dosing it would be highly recommended. It did clear up but I was still having issues of cloudiness from the sponge in my filter and the tannins from the wood was a lil on the darker side for my plants than I’d like. So I decided to siphon out the tank as well as cleaning the filter and this time ACTUALLY cleaning the substrate until it was clear enough and the picture where its clear water but still cloudy was when I filled the tank back again and added the dosage. After the next day it was so clear although yes there was still some tannins in the water that had leeched overnight its the perfect hue for me to feel comfortable with for both my loaches and plants. It does clump up the particles like it said it was since I am running a smaller filter since I also have some otocinclus catfish that will benefit from the algae that will grow but you can just siphon up those clumps. All thats missing is for my almond leaves to come in to create that natural habitat for my kuhli loaches and have a lot of hides and places to explore. For whats its worth its inexpensive and gets the job done.

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.

This stuff is wonderful! My beta has always had a little cloudy water. I’ve tried to balance all of the chemicals to no avail. But I added exactly what the directions said and it was clear overnight! If you’re considering this purchase, I highly recommend it and I don’t think you’ll be disappointed
