Product Description

Seachem’s Clarity water clarifier for marine and freshwater is the ultimate solution to remove cloudiness from your tank or aquarium.

For over three decades, Seachem has been a company rooted in sound science. Our experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist - Dr. Leo G. Morin (Founder) - recognized that the available solutions to aquarists problem wanting. This resulted in Seachem’s very first product: Cupraplex (today known as Cupramine). Over thirty years later Seachem is still approaching old problems in a new way.

Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

Important information

Directions

Use 1 capful (5 mL) for every 80 L (20 US gallons). In some situations the cloudiness may increase after adding Clarity™, however this is normal and is a sign that Clarity™ is actively working. Rapid clarification will follow (1–2 hours). In the case of chemical or particulate clouding clean filter floss or cartridge after tank clears.

I'm actually shocked by how well this worked! There's no fish or critters in my tank yet so I did a second dose the following day. I don't think it needed it, I think I was just being impatient but either way, it worked so good!!!! Just look at my before and after pictures. My tank was so cloudy and within 2 it was crystal clear!

 Great product. Just be sure to use half of the recommended amount as it can potentially be lethal to your fish as some species are more sensitive than others. You will have to wait a bit longer for the product to take full effect due to this, so keep that in mind. It can take anywhere from a few days, to a few weeks. In my case, it didn’t clear up my water up until 2 weeks after I had used it. The water in my tank was always cloudy even after weekly water changes and I couldn’t get it to be crystal clear, which was very frustrating. I am also aware that the size of my tank should be bigger (I will upgrade as soon as I can) and was definitely a huge factor towards my water quality being less than ideal, so I definitely took that into account before even considering giving this product any kind of review. Wish I had a before video of my tank to show how bad it was, just know it works well if you use it carefully and are patient. Very pleased with this product, my goldfish tank (the dirtiest tank with the cloudiest water because of how messy goldfish tend to be) is now looking good!

 This works for clearing up our tanks, help with settling floating matter, extends the cleaning period and gives a great look for all our tanks. Comparable pricing, easy to follow instructions and just need to get use to the dark or smoky look when you first add it to your tank, it clears out fairly quickly.

3.0 out of 5 stars Seachem is normally a great product. This, not so much
Reviewed in the United States on August 4, 2020
Size: 8.5 fl ozVerified Purchase
Snake oil! This product does not do as advertised. I had cloudy water due to the addition of a piece of driftwood that I didn't get cleaned properly and lack of tank maintenance due to being in the hospital for an extended period. I was horrified when I got home as my tank which is normally crystal clear was trashed. I got this product as a quick fix to no avail. Proper tank maintenance cannot be fixed by a product in a bottle! If you're adding any type of wood to your tank, boil it if possible or soak it for a week to get the tannins out of the wood.

I've used several other brands of aquarium "de-clouder" and this is BY FAR my preference.

This brand is the best deal because YOU USE MUCH LESS product per use. LESS THAN A CAP-FULL for 10gallon tank. The product works very well. Its not instant (mine was overnight), but good quality takes good time.

Definitely try it out.
