Not a new tank, it’s established.** A: It’s a polymer. It will bind particles together so your filter can catch them. Might need to get a smaller micron filter sock and/or a protein skimmer. Your filter probably isn’t turning over your tank fast enough. **Q: How is this product different from Seachem Pristine?** A: Stability, Clarity and Pristine are all different combinations of bacteria that perfom different function in your aquarium. I routinely (once a month) dose with all three to keep my biofilter in optimal condition. **Q: Can this condition the water to make safe** A: No, you would need Seachem Prime or stress coat for water conditioning. **Q: Safe for scaleless fish such as green spotted puffers?** A: I have used this product for 15 years and I have NEVER lost a saltwater fish and I have had Various breeds of clownfish,All Invertibrates,Clown Triggerfish,bamboo sharks and many more.Just to let you in my experience do NOT use too much at a time Don't get freaked if it clouds up your tank within the first 5-10 minutes,it is just doing its job wait a day or two then use a second dose until the tank is clear.Then my recommend product is prime and especially the product Vibrant which is a lifesaver and love and trust it more than any product I have used.It is around $30-$35.00 and definately worth the money because I only use it 1 time weekly.Hope this was helpful ## Customer Reviews ### ⭐⭐⭐⭐⭐ Crystal Clear Water Every Time *by M***� on July 14, 2026* I’ve been using Seachem Clarity in my aquarium, and it works exactly as advertised. It cleared up cloudy water much faster than I expected without bothering my fish. Just follow the recommended dosage, and you’ll notice a big improvement in water clarity. A little goes a long way, and it’s now a regular part of my aquarium maintenance. Highly recommended! ### ⭐⭐⭐⭐⭐ Works great *by T***A on July 16, 2026* Great product for your fish tank ### ⭐⭐⭐⭐⭐ Be patient and be careful *by I***. on June 8, 2021* 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! ## Frequently Bought Together - Seachem Clarity 500ml - Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1) - Seachem Pristine Aquarium Treatment, 500ml (001438) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/10931593-clarity-500-ml-17-fl-oz](https://www.desertcart.hk/products/10931593-clarity-500-ml-17-fl-oz) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-17*
