This time it was completely clear! WATER! No smell, no color of any kind. I did give it a good shake!So I poured the whole bottle into a cup and only at the end a few white flakes came out. I put it back in and tried to give it a good shake, but nothing worked. Still water with some flakes on the bottom. I wonder if more minerals were stuck to the bottle.The date on the bottle is 2018.Returning and not buying again. ### ⭐⭐⭐⭐⭐ Recommended at my LFS *by C***A on Reviewed in the United States on April 23, 2020* This was recommended by someone at my LFS for use in a tabletop fountain with Red Cherry Shrimp, where I'm testing out trying to use RO water. You can use this by the drop, but be aware that if you squeeze to get that drop a lot more than one drop will most likely come out. That happened to me, and the TDS was over 400 the next day. I just did a pwc (partial water change) and then in the future dropped over another container. You could also just use a plastic pipette. It's only an issue now because I'm dealing with such a small amount of water. ### ⭐⭐⭐⭐⭐ Good product *by S***T on Reviewed in the United States on January 15, 2022* Great for those tanks with RO water only --- ## 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.vu/products/30939243-kent-marine-00590-liquid-r-o-right-8-ounce-bottle](https://www.desertcart.vu/products/30939243-kent-marine-00590-liquid-r-o-right-8-ounce-bottle) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
