Pure Original Ingredients Calcium Carbonate (1 lb) Dietary Supplement, Food Preservative, Acid Neutralizer

This is a KEY ingredient in natural DIY toothpaste. I’ve made about 6 tubes of toothpaste already and still have enough left for about 4 more tubes.It’s a great value for the money. It comes in a fine powder, so mixes well with the other ingredients and is white in color (as toothpaste should be).Stop getting store toothpaste. Make your own for white, strong, lovely teeth.

PROS:* Mixes easily.* Works great as a flocculant. It definitely removes a lot of suspended particles in the water and will help deliver extra clear water for those with such an issue. Removing the suspended particles (proteins/foods) also means that water is cleaner from a nutrient perspective.CONS:* I hate the bag container. Hard to scoop out stuff without making a mess or using a funnel, but not a deal breaker. Good value.USE:I recommend the use of this as a flocculant for saltwater aquariums. It is hard to overdose.Here are excerpt instructions from a thread on water clarity and cyanobacteria treatment in a saltwater aquarium on a popular reefing site (I don't know if I can include links in reviews):"Select a clean container, one that is resealable and able to be shaken. I use an old creatine bottle.(Yes, I am on the GAIN TRAIN)For 500ML of solution, add 10 level tablespoons of powder to roughly 425-450ML of RO/DI water.Shake the bottle up, and let it sit for two hours. After which, it will be ready to use.Now, I don’t believe that you can overdose with this product, but a good recommended dose is 5ml per 50gl of aquarium volume.Be sure to shake up the bottle prior to each use as the powder can settle.The best time to add the solution to you aquarium is after conducting maintenance such as blowing off the rocks, cleaning the glass, siphoning the sand or conducting a water change. Ideally, you should be doing all of the aforementioned maintenance items during a water change, but that discussion is for another time."

Sugar free alternative of any acid reducer

I use this for my tortoise and toads calcium. It's a great price and lasts a long time.

Good stuff, bag was already leaking a bit when it got here but was contained in another plastic bag, so messy, but not till you opened it lol. Overall a good buy though

I've been using this in the recipe of a tooth powder for brushing our teeth. It's been working really well! Usually, during dental cleanings we are told we have staining that they work to remove, but since I stopped using OTC toothpaste and making our own, our hygienist isn't struggling with staining. Go figure. This product has a super fine powder consistency that works well for my application. Big thumbs up!

I use this as a supplement to add to my dogs home made dog food.

I use this to make my coffee "cowboy style". Use this instead of egg shells to settle grounds and reduce acidity of coffee.
