brown AP solution is a sign that its saturated with copper. you have too much metal and not enough solution. you can decant the solution into another container and and add fresh solution or place the air source in the old solution and wait for it to clear to green and then replace it. instead of adding more oxidizer, add more hcl.
 
onewally,
I see a gold button in your hand in the near future, looks like you have been busy learning, good job nice foils keep it up.
Laser Steve's web site has a document that explains the copper II chloride leach (HCl acid peroxide), how it works and how to rejuvenate it.
