I've read that gas production increases with the concentration of potassium hydroxide up to 28% ( by weight). If that is true and current is not an issue than you should add 2.34 lbs. of koh to one gal. of distilled water which weighs 8.34 lbs. Is this correct? That is a lot of teaspoons. The article also stated that after the 28% concentration of koh gas production would decrease.
