Forgot to mention the ratio, you had 1:15. I can't find my instructions, but I did find one that had 1 part ferric chloride to 4 parts distilled water.
It has been at least 5 years since I made my batch up and it still works. If the solution is not up to the line on the pipe, I just add more ferric chloride.
