I am not sure why you are starting another thread on the same subject. Have you actually read any of the advice I gave you in your other thread based upon my experience using the 12” version and actually used that advice? If you haven’t, then read it and try it, because the advice I gave you came from my trial and errors starting out with the vacuum filter last season. It should not make any difference in how you use it between the 9,12,18” size vacuum filter. I think your problem is that you are NOT using enough Maple DE in your syrup.
