According to them it is a slightly stronger concentration of cleaning agent vs. the larger bottle. However this is the old spec, they have recently changed the concentration so going forward the small bottles listed in this product page will only treat up to 15 gallons. So if you do purchase make sure when you get the bottles you check to treatment listed to see which concentration you received. The ones I got were the previous generation treating up to 21 gallons which works for me.
