I know we are in different area but Pinch a penny here in fort myers carries both PH Plus ( Ready to go Alk) and Calcium hardness ( Ready to go also) both are like 30$ for 40lb bags. Great thing about these are they are both like 99.8% pure so no real additives or anything. Hope it helps! You are lookign for these color bags with 99.8% Sodium Carbonate and 100% calcium Chloride (think dow is like 96% with filler)

I've been using Leslie's pool supply hardness plus with no I'll effects for over a year, I'll note that after mixing 2cups/1g some precipitation settles on the bottom after a day, I filter out the precipitate using a coffee filter twice.
For alk I get a 13.5 arm and hammer baking soda from Sam's, I think its $7, i use 2.5cups/1g and just bake at 350° for 1.5hrs

These chemicals are ready to go you do not need to bake any of these, its liek pre packaged soda ash. 2.5 cup per gal for cal and 3 per gal for alk. one 5lb bag of each has lasted me over a year. They are nicely concentrated and need to be honed in like me using a doser and you will have a little bit of sediment/settle on bottom of containers, i just stir every other day and easy as that. under 40$ for 2 part for the year for me 
. Any questions LMK!

I like this but I'm concerned. Aren't you afraid of heavy metals or any other impurities? It only takes a few ppm to kill a reef?

This was also a concern of mine...is there any info on how much if any these products might contain?
I've used Dow Flake for years with good results. Still have half bucket but it's solid block now. So kinda hard to break apart. So thought I try something new so far it's working just as good as Dow flake. Might add that this is a 180 mixed reef running with no water changes in 5 or more years. Been carbon doing vinegar and sugar to take care no3 and pos4. Thanks to Cubed Reefer for the heads up on PNP.

they have it on the bags guys
Calcium is 100% pure (calcium chloride) i belive dow flake is just under 97% or around there
Alk is 99.8% Sodium Carbonate
Both are the purest additives I have found outside big box 2 part pre package

5 years? How is that possible? what about replacing trace elements? Are you running a algae scrubber?
Just replacing calc and alk two part daily an top off with ro water for evaporation. An adjust salinity when needed. Not keeping hard acros just lps zoas leathers one Ritter nem 3 clowns arch eye hawk jellow wrasse green file fish and clean up crew. Dosing vinegar & white sugar. Sure I have had ups an downs but with bad back just had to try or get out of hobby.
Happy reefing
