Does this require the addition of calcium nitrate?

Calcium nitrate is helpful, but a good cal-mag (calcium-magnesium) mix is essential for solid growth. The typical cal-mag has enough nitrates in it to do the trick. I use XNutrients CalMagX, and it is awesome. Hope this helps.

just adding my 2¢ here, it does need to be melted and filtered before use in products.

No. Just solids and chlorine as far as the package says. I think you need RO for that.

It contains calcium as well as sulfur. Both are inorganic elements, but in my view are suitable for 'organic' gardening. If you were to put greensand, granite dust or dolomite on your garden these are also inorganic compounds.

There is no calcium or dirt build-up after use. The unit will detect low water level, when it has about 1" left, and the unit will shut itself off. Then I dump the remaining water and fill it with new.

Yes--add 1/4 c to bottom of dishwasher-takes all the calcium spots off the dishes

no, it was not required for my whirlpool softener, nor did the bags say anything about a gravel base. I suspect that is specific to the softener and not this resin.

There is no mention on the bag if it does or does not contain calcium. It says no added dyes or chemicals.

This item does not contain Calcium Nitrate but the premixed version of this product can be found here: Hydroponic Tomato Fertilizer 20-18-38 - 2 Lb.

Im really not sure of the answer...however, I did use mine from last summer at the beginning of the season with no problems. I even used the calcium water that had stayed in the fridge all winter. No issues.

No just the dissolved solute count. The hardness would depend on what those solutes are, for example you can have hard water from calcium salts, but you can have high nitrates or iron, and the water will not be hard, just dirty

Yes you could add calcium to the water to raise the alkalinity of it. Baking soda does this as well.

I believe it must be an error because the ingredients on my bottle say it contains only cellulose, stearic acid, cros-carmellos sodium, magnesium stearate and also says on the label "contains nothing other than listed ingredients" . I purchased this product specifically because I did not want one that contained calcium and I am convinced from the ingredients that it does not. Perhaps you could notify Amazon of the description error.

I have no idea and I don't believe the nitrates are listed on the package. I threw it out but as I remember a serving was a tablespoon. It is not organic and tastes AWFUL.

There is calcium citrate in the product. The label reads "0.5% Min.-1.5% Max." Sorry. Good luck in finding something that works.

I believe it does, though I was not present when it was installed. We also added the (calcium?) filter to hopefully keep it from clogging up.
