Looking further, I found the below document on the Celeste Sani-Pak aviation lav chem product. (Bronopol based) Looking at recommended dosing on page 4 on the below doc, I think we would only require 6-8 grams per toilet charge to meet the "Long-Mid Haul Standard Servicing Interval" dosage.

I see a 100 count box of 8gram packets on ebay for 60 bucks.. That works out to 60 cents a charge... That's way cheaper than any other toilet treatment I have seen. Going to give it a shot.
Sani-Pak toilet deodorant – developed over 40 years ago for military use – is recognized worldwide as the benchmark in aircraft lav chemical deodorants, and today is also used in rail, mass transit, marine, recreational vehicles and portable toilets.
SP-77000 Series (powder) – Sani-Pak powder is the grandfather of lavatory chemicals. Single use water soluble packets or larger tear open tubes offer an easily controllable and measurable way to deliver the power of Sani-Pak chemical. Unlike other powder products, Sani-Pak uses two types of water soluble film for optimum solubility.
