Works wonders
My favorite aquarium water clarified. I have goldfish and this gets the water crystal clear. I mean clear clear. It does get cloudy at first as its working but then bam, clear. I have live plants and it never hurt my plants nor the fish. The bottle was a decent size, because I was buying the smaller bottles of this brand and loved it so much I had to get the bigger bottle. Totally effective in my 30 gallon goldfish tank.

Works great
This product is great it does exactly what it’s supposed to do I’ve used it twice and each time it took about a half a day and the water was Crystal clear. This item is definitely worth the money.

This ruined my 6 gal cube aquarium by causing a white bloom/blossom all over the tank?
I have 2 of the 6 gallon cube aquariums for my Bettas and I set them up exactly the same, on the same day … but the tank on the left became cloudy so I ordered this stuff. Note the tank on the right is perfectly clear (the deep tan walls behind it make it look darker than it really is) This is 14 hours later and it appears to have ruined my 6 gal cube aquarium by causing a white bloom/blossom all over the tank?UPDATE: Manufacturer emailed me to say that I needed a filter on my tank, which I did not have. I did a 3/4 water change, removing most of the white dibris, and it’s almost clear now.

Insane!
It’s wild how quickly this stuff clears up the aquarium. Just a few drops and you can watch the water fog disappear. Makes me wonder what I had growing in my tank…

Kills fish even when used exactly as instructions stated
Well I started with slightly cloudy water that was honestly not horrible but I wanted perfection. I followed all instructions on the bottle for use. It seemed as if tank was clearing quickly and I was going to be pleased with this product and the results of such. After loading dishwasher (approximately 15 minutes or less) and returning to take a look at my tank, I already had 2 dead fish and two that looked to be in distress. I have completed an emergency water change and now I wait. All water levels prior and post mass casualty event were showing up as perfection.

Unsure
It didn’t clear up my tank. We cleaned the whole aquarium, all fresh water and after 2 days it was so cloudy you couldn’t see my 8″ Oscar. Ordered this clarifier, have used it twice and it’s still cloudy.
