Calcium Carbonate Powder (Food Grade) (Fine - Smooth Chalk Paint) (Toothpaste Additive) (Eco-Friendly Packaging), Available in 4oz, 11oz, 1lb, 2lb, 50lb

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. "

Yes this worked as a pH tamer for my acidic foods and drinks. The only one problem I had is that at the very end, that chalky texture stays in your mouth and affects your tongue, or my tongue rather. It felt like having some Tums in my mouth that left a chalky residue. This definitely works. What I was worried about is I am unsure if it is safe or what amounts is safe to have daily. I use an 1/8 to 1/4 of a tsp in my 8 oz. coffee. If I have 16 oz. I do 1/4 tsp to little bit more, but under 1/2 tsp. Because I am unsure what amount to put, I try to keep it low. Compared to coffee tamer, I seem to get a better result, aside from chalky texture in my mouth at the end sips. It is definitely cheaper.

This stuff is the bomb. I made homemade gesso with it. Works amazing on canvas
