Just a note on using chemicals. Always mix them exactly as the label says and they will work if applied as directed. Also, mix them immediately before you use them and do not leave them in the tank for use tomorrow. Every chemical has a PH it likes to dwell at and mixing it with water of a different PH will alter the chemical and render it ineffective. The greater the difference in PH, the quicker it will break down the chemical in the tank. Something about atoms in the chemical bonding with iron atoms in the water. IIRC, name brand chemicals, the instructor mentioned Roundup, have added buffers to reduce the problem but generics usually do not. He said some chemicals can lose over 50% of their efficacy in 30 minutes in a tank with water of a large PH difference.
