I think, I have it figured out. two reservoirs, each with a full capacity of 70gl, Let's say 65gl each. 6.42ml of H2O2 per gallon. 65gl + 65gl = 130gl x 6.42ml = 834.6ml every 3-4 days. I paid 25 bucks for 1gl or 3.78L.From one bottle I can get 4 treatments for both reservoirs, and use the extra 44ml in my aero cloners, and to clean tools. $$6.26 for each of the four treatments. 30 day month, dosing every 4 days = 7.5 Doses each month or $46.88 per month approx.
Did I lose ya?
Sorry I am baked and like math. lOl
