I knew the River was very silty and would easily clog my sawyer filter. One needs to add a flocculant to this water to make the suspended particles stick to each other (to make them heavier than water so they'll sink to the bottom) There appears to be several kinds of aluminum compounds that are used as a flocculant. Water Wizard (poly aluminum chloride) is a well known product among the Grand Canyon rafting groups. It is a little expensive but at the time it wasn't available. It is mixed at a dose that is 80% of the maximum suggested dose. The more common chemical that many water treatment plants use is aluminum sulfate. In my readings, the maximum suggested dose of aluminum sulfate is 50 mg per treated liter of water. I chose to use 80% of the maximum dose so I dissolved 100 mg of this into 125 mg of purified water (used a postal scale to measure and bought water from a grocery store). I had to shake it vigorously and use a chopstick to break things apart in the bottle. It did not dissolve right away (even though the solubility properties of aluminum sulfate indicated that it would easily dissolve). I left this overnight and the next morning everything was completely dissolved. With this solution the dose is one drop per liter (one drop contains 40 mg aluminum sulfate). I initially tried this at home: mixed dirt and clay in one gallon of water, then added 4 drops, shook vigorously then let sit for 30 minutes. It did cause most of the silt to settle but it still looked like pale grapefruit juice. I did this several times with the same result. In the Grand Canyon the Colorado was very silty(looked like chocolate milk due to the high amounts of run off from snowmelt). One of my friends also brought Water Wizard My aluminum sulfate and the Water Wizard seemed to be equally effective. (All 5 of us came to the same subjective opinion) For some reason, the treated Colorado water seemed to be clearer than my water that I treated at home. I did find that the longer that I let the water sit, the clearer the water was. If I let it sit overnight, the water was almost crystal clear by morning. I'm quite happy with my purchase and I learned a lot about this aspect of backpacking Review: Great Alum Soak for Aquatic Plants - I use this product to give my new aquarium plants an alum soak to get rid of pests before I add them to my tank setup. So far, it has worked great, as I have yet to find any pests (planaria, snails, etc.) in my aquarium. ## Features - Pure Original Ingredients Aluminum Sulfate is iron-free - Add to gardens & planters to acidify the soil - Use as a hide tanner, water treatment, or cloth dye - Always pure ingredients with no additives - Packaged in Utah, USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07531134Y | | Best Sellers Rank | #40,760 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,179 in Garden Fertilizers | | Brand Name | PURE ORIGINAL INGREDIENTS | | Customer Reviews | 4.5 4.5 out of 5 stars (890) | | Global Trade Identification Number | 00195507032613 | | Item Form | Powder | | Item Type Name | Soil amendment | | Item Weight | 2 Pounds | | Manufacturer | Pure Organic Ingredients | | UPC | 195507032613 | | Unit Count | 32.0 Ounce | ## Product Details - **Brand:** PURE ORIGINAL INGREDIENTS - **Item Form:** Powder - **Item Weight:** 2 Pounds - **Manufacturer:** Pure Organic Ingredients - **UPC:** 195507032613 ## Images ![Pure Original Ingredients Aluminum Sulfate (2 lb) Iron Free, Soil Additive - Image 1](https://m.media-amazon.com/images/I/71C05qRyHoL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Used to remove particulates from murky/muddy water *by M***N on May 18, 2023* In preparation for an upcoming backpacking trip in the Grand Canyon I knew that we would have to use water from the Colorado River to drink.

So far, it has worked great, as I have yet to find any pests (planaria, snails, etc.) in my aquarium. ### ⭐⭐⭐⭐⭐ Exactly as expected, would recommend! *by M***Z on March 31, 2026* I had never used this compound before but when I needed to tan a sheep hide this was the product needed. It was the weight expected, worked as needed and arrived in a timely manner. Color of this compound is white in a paper bag lined with a coating to prevent moisture. I would recommend this product and seller.
