Right....first number is nitrogen, don't want alot of that, second is phosphate, and third is potassium. The liquid will probably work quicker too...it took mine about 3 weeks to even begin to develop but it's looking good now. I just carried the bags out about 10 feet and laid them on the bottom in about 2 feet of water, tied a string to one corner of the bag and the other end to a snag on the bank, then split the bag open in a cross and removed the center plastic. It is dissolving slowly and seems to be about half gone.
