Calcium Carbonate Powder | 1 Pound - 454 g | Food Supplement | Highest Purity Limestone | Heiltropfen®

Great.

Thankfully completely tasteless, no nasty mintiness (I hate mint).It's so fine it dissolves super-fast and the old man for whom I'm a carer gets super-fast resolution to his indigestion (I also mix in a teaspoon of Bicarb). Much better and cheaper than tablets. I have a fine weighing scale down to 1/100 of a gram which helps, as 5 tablets of 500mg of calcium carbonate is easy enough, but 2.5g of this stuff is actually very little and you don't want to be whacking your kidneys with too much.

Very easy to digest.

Wow, really good quality

I recently found out I have a problem processing oxalate in plants foods which has been causing joint pain, inflammation, urinary urgency and pain as well as a host of other symptoms. Taking this binds the oxalate my body is trying to excrete and helps the process go slightly more smoothly, ordering my second tub today! And never ever eating spinach again!

This product is no doubt good for your health, but ideal for freshwater aquarium. Due to the purity, a good level of KH and GH can be achieved without raising PH drastically. Unlike sodium bicarbonate, this product provides some GH or soft lime and can be successfully combined with aquarium salt for freshwater (sodium chloride) and only raise PH slightly and KH maintaining truly soft water without the use of tannins or acids. Calcium carbonate doesn’t seem to be available for aquatic use, only sodium bicarbonate. Making this product very useful indeed.

Great for intended use. I personally use it for my aquariums and plants, and it has been satisfactory so far. I have 8 aquariums and still over half the container left. Lasts for a long time and would definitely recommend, AND buy again.

Great way of getting a good dose of calcium and also the powder is really easy to dissolve in water with no aftertaste.
