So I just purchased the AquaBoost a few weeks ago. I have been adding it to my 5 gal water jug and leaving the 7gal water jug plain. I battle algae growth in the water jugs and have resorted to a quarterly bleaching ritual to try to freshen them up. I've found that the AquaBoost 5-gal jug is totally algae-free after 3 refills! I've been able to spray with my hose the remainder of the algae growth to wash it away and am left with a totally sparkly water jug. (and of course, happy chickens!) My girls love it and I find that their AquaBoost water is the first to empty from the plain water. I'll definitely be a returning customer to Buff Clucks <3
