What kind of sorcery is this??? It works so so good, makes my red eared slider’s water crystal clear in a matter of hours. Nothing makes it look as clear as this product and a little goes a long way so one bottle lasts a while, i definitely recommend buying!

I have a 3gal tank and a seasoned aquarium owner for years with various size tanks. Lately I've had issues with relentless cloudy water with the constant outdoor ambient air temp changes. After small water changes and things I finally decided it was time to find some water clarifier.
I used about 1.5ml for my tank and within an hour it was clear. I later changed the filter and did a small water change and it's crystal clear.

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.

Reviewed in the United States on December 16, 2023
I brought this because I couldn’t hardly see anything in my tank thanks to the green algae water. I did two treats (second treatment after 24 hours and a water change because I didn’t notice any different). Well 5 days later, my water became crystal clear. I did nothing in those 5 days. Not sure why it took this product this long to work (I didn’t add or do anything with my tank in those 5 days so it has to be from this product). You can see the results in the picture.
My tank is 55 gallons and I put in 5ml both times.

I am only giving 4 stars though because of the length of time it took. I can see people getting impatient and continuing to dose in that time. Seriously I had already given up on this product and was waiting for something else to come in the mail to fix my cloudy water when my water just became clear.

Reviewed in the United States on February 6, 2021
Let me say first I'm VERY attentive to my tank. I have to be careful to not clean it too much or too often. My water became brown cloudy. I used what I had which was "Clarity". It may have helped with the brown but did nothing for the cloudiness, not enough to notice. A friend uses this product so I ordered immediately. In pic #1 you see my starting point. Pic #2 is 24 hours after first dose. As per directions I did a second dose. Look at pic #3!! My pics don't do justice!! (Also, I took pic 3 right after feeding sinking granule food. Focus on the back of the tank). This water is so clear it almost seems white!!! It's BRIGHT!! I read bad reviews where some had dead fish. One lost them all overnight after one dose. So, that told me this stuff is potent. 10 gallon tank so 1 ml is my dose. That's on the INSIDE of the cap. I took the advice of one who said they add it into the back of the filter. I did that with floss removed. I could have done like I do with other liquid additives which is pour into filter "waterfall" followed by a gentle stir of the water. I cannot express how thrilled I am with the results of this product!! I've already done the long list of other things we do including water change but nothing worked. My only real advice is be vigilant when measuring. I can see how even the slightest "too much" could kill fish. I will tell you after only one dose, while still a bit cloudy I noticed a BIG change in the behavior of my tetras!! They were playing!! No kidding!! The school was swimming fast back and forth at the back of the tank!! I've never seen them do this before!! They were not in distress, they felt good!! Happy healthy fish!!! (Fish do have personalities, ya know! ????) BUY THIS PRODUCT! I wouldn't even wait for problems. Buy it to have on hand when you need it because you will. Not my first experience with cloudy water though I haven't had several occurances either. HAPPY!!! WOOHOO!

Reviewed in the United States on April 13, 2024
I used this liquid a few weeks ago, because my water just did not look polished. The water turned milky for 2 days. On the third and fourth day it improved a bit, but the water did not totally clear up. I did a major water change instead and it cleared the water up.
