Dave B,
Is there a problem with asking questions on topics that have been recently written about in your magazine? Maybe I am taking your post the wrong way?
You are new. Do a search using Bob's member number as criteria & you will answer your own question.
As long as it's pond related it is welcome here.
If you had a magazine with a related article in a recent issue would you not reference it in this thread?
I've been following this thread also & thought of the article but dumb me it didn't occur to mention it.
Wish I had done so now so Bob wouldn't of had to.
