10 lb Food Grade 97+% Calcium Carbonate from Ground Limestone

Bought calcium for the chickens as egg shell became thin. Now egg shell quality has improved and the calcium appears to be working.

Tums and other calcium carbonate based antacids seemed way too hard to chew, so I tried this. I use a tablespoon mixed into a small cup of water and it works just as well.. if not better.The only problem is that it's difficult to mix and quite chalky. Some is always left in the bottom of the cup and you may need to pour in some more water to get it out of the cup. But that's unavoidable given the silty nature of this product. If they had something more like instant coffee that would be great. But this works fine.

We made a thick paste of this product. Painted it onto our pavers. Let it set up and dry. Then we scrubbed the pavers with water and a heavy duty nylon brush. Almost all of the stains came out of our large paver driveway. We had two spots where the roofers dropped gas and hydrolic fluid that took two applications but it worked.

I add this to peat moss to put on top of my CVG. It works well.

Quality is definitely food grade and for what I paid , the best overall value. You get two 5 pound bags.

I've been making and using DIY Toothpaste for almost 2 years, this Calcium Carbonate from Ground Limestone is the main ingredient. The mix is amazing, my new dentist and hygienist are stunned at the great condition of my teeth. Excellent product.

I am a vegan so this is a necessity. I mix a scoop with my protein shake in the morning. No yucky taste. I highly recommend this product.

Purchased this for a well water PH adjustment system. The soda ash did not stay dissolved in the solution. I mixed it as well as I’ve mixed any other brands. It was fine for a day or two but after about three days all of the soda ash had settled on the bottom of the 35 gallon tank. I contacted Duda Energy (the seller) about the problem and they basically told me they don’t know anything about this product and couldn’t help me.
