I was skeptical after reading some reviews here but we have a fluval spec 5 that was recovering from an algae bloom (solved by shutting off LED lights and covering the tank with a blanket for two days). But the water was still cloudy even after a partial water change. Measured out the correct amount (1.5ml) and a few hours later my tank water looks clearer than it EVER has.
Not for me

I usually like this brand of aquarium products,. My tank had a slight cloudiness to it so I purchased this it was supposed to make water crystal clear, in approximately 3 hours. NO!.. not only did it not clear it up but it made my water SUPER cloudy! for days. I couldn't even see thru the water. What a hassle, so I ended up having to do almost a complete water change. So I will not be buying this again.
I'll order again

Item works very well. The water clears quickly. Fish are not bothered when added to water.
Did not help

I tried this product several times. It did not help. Ended up putting another filter on my 55 gallon aquarium. Gold fish are in tank and were in a clear 30 gallon before.

This product helps your filter become ultra efficient; if your filter is the problem it probably won’t work well. It breaks downs macro-bio-molecular compounds and makes it easier for your FILTER. Usually at first the water will get more cloudy— this is the “break up” of the biochemical matter. Than your filter takes over and cleans the water. I would recommend following up with a monthly Fluval Bio clear water. These working in concert will keep water crystal clear!

Okay so I have FX4 and thought Fluval knows what they are doing. This product is horrible and will muddy up the water. Fish also reacted to it as they didn’t like it. I won’t use this past the one dose. Both this product and the bio - clear product by Fluval are very bad and do the opposite of what they need to do.
A great clear water treatment for aquariums

I will most certainly buy this again, it's great. The price is good and it didn't bother my fish.

I had a months long battle with cloudy water in my 39 gallon tank. This product cleared the water in a few days and the tank has remained clear for weeks now. If normal methods are not working for you, I would recommend giving this a try.

Did nothing for my tank...I wasted valuable $. I did everything the directions told me to do...to the letter...and nothing changed.
