Sorry, don't know about your specific water softener brand. I use the Morton's in my system and it works fine. Hope this helps.
Yes, for my softener I was told my the distributor that the crystals were preferred.
Te salt tablets are not table size salt pieces
Morton® Pure and Natural™ is made from all natural, high purity salt crystals. The natural solution for softer feeling skin and hair, less buildup on appliances and easier cleaning when used in a water softener unit. We are unable to recommend the use of this product in a fish pond. A reputable pet store or a local veterinarian should be consulted for the best product to use in a fish pond.
No. Not purified for human consumption.
The concentration of iron (and other specific) ions in water is affected principally by (1) total ion concentration, (2) the presence and abundance of ions of potential compounds, (3) pH and (to a lesser extent) (4) temperature. Salinity, per se, will not predictably lower the iron concentration in water. In a typical water treatment system, salt crystals such as these are used to create a brine solution which "regenerates" (periodically restores the effectiveness of - by backwashing / rinsing) polymeric resins ("beads") that do attract iron ions and 'pull' them from the treated water. Hence, a water treatment system is comprised of two or more vessels including a brine compartment, one or several 'contact' tanks (with resins), perhaps a neutralization (pH adjusting) tank with calcite or other minerals, etc. Sometimes the number of tanks is reduced by loading mixed beds (layers) of various resins and minerals in fewer vessels.
It looked very clean to me.
Yes. Picked it up myself from the store and used it up as soon as I returned home. Easy, simple and done.
It is the chemical composition of salt which makes it effective in the regeneration of water softener media. So long as the salt can be added to your brine tank and solubilized, its physical form should not make a difference.
No damage to pipes
