Like I said, quit digging. You're starting to make a fool of yourself.
From the first document you referenced but apparently didn't read or perhaps understand:
"Examples of dosaging amounts of BCDMH biocides for the corresponding amounts of water to achieve 1 ppm bromine residual are as follows:"
1 ppm. Bromine tablets that the OP was asking about deliver 30 times that amount. Can you understand that there is a difference between the reactivity of one dosage that is a minimum
of 30 times greater than another? I say a minimum because with the cannister system the OP was asking about, or JD's and your recommendation to just throw a couple of bromine tablets into the water strainer completely ignores the reality that bromine tablets are designed for FRESH water, not SALT water, and the presence of organics and NaCl results in a very different level of solubility. That's why the system you reference but don't understand specifies expensive equipment to ensure that you don't have more than 1 ppm continuous presence of the element in the water. Or are you suggesting that the amount of this element the copper piping an a/c system is exposed to has no impact on corrosion?
Tell you what, Rick. Don't answer. Save both of us and anyone else suffering through your continuing defense of ill-informed nonsense the grief. As usual, you respond to a simple question from someone on whether they can use bromine tablets to suppress algae growth with descriptions of systems like the one referenced above that due to its complexity, cost and totally different dosing capability has no relevance to the question of the OP, or any possible solution of value to a trawler owner.
