29 ounces does not sound right.Following this chart and converting to oz. I would use 29.6 oz Capt. Jack Conc. to 1 gallon of water or 1.85 oz to 8 oz of water (yield about 10 oz of spray) right?
ps... sorry for bringing up an old post but I recently bought a bunch of Serama from a few sellers and I was shocked that Most are suffering with mites. Not only is the Capt. Jack's more affordable in the short term but the lower concentration makes it easier to measure in my opinion.
