I.e. was the ratio of baking soda comparable to the amount required to raise alkalinity from KH 6.0-7.0 to KH 11 in sea water at SG 1.025-1.026?

I am somewhat perplexed by posts made on another board regarding a thread that was started on ReefAquariumGuide®. I offered a goodly amount of information regarding baking soda, its pH properties, its proposed role in marine aquarium keeping, calcium hydroxide, borate, etc. Thus far the only bone that was picked was from "someone" ostensibly calling a baking soda company. Was there a problem for this "someone" calling their brother in-law chemist at the 20 Mule Team® company?

The scoop from an Elos kit says .4 ml on the big end and .15 ml on the smaller end. I would assume that .15 plus .15 equals .30 or has math changed since I went to school?

I have no clue if the .30 ml of baking soda added to 10 ml of water would be enough to raise alk 4-5 dkh (or even 1 dkh for that matter). Haven't done the research for the math on that one. I simply guessed that if there was silica in the baking soda that two small scoops would be enough to show up on a test kit and allow me to even perform the test. Once you start adding stuff to the mix it becomes a chemical fizzy. Took me 3 attempts to get the test done correctly without blowing the top off and losing fluid and forcing me to start over.

Only two or three people from the other forum have even read this thread. It's not like there is a link in that forum to this thread.

I do understand that you had stated that silica is "generally" the anit-caking agent of choice.

I guess I can also assume that you don't know what anti-caking is used in A&H (if there is one) or you certainly would have stated it by now.
