I just ordered some pure nickel strips for plating.
I found the following article:

which suggests using a 15 micron polypropylene filter.
And I found just such a filter here:

If you are using a single anode and single electrode, you could you could buy two filters and place the anode and electrode in the socks to keep the solution clean. Or, you could buy a single sock and periodically pour your nickel solution through it.
So, I am wondering if the debris is causing issues, and what Jim or anyone else is doing about it.From your photo there is a lot of debris from that Anode. In that "Quite a nice little 60 -70 page help guide" they mention this. They say agitation of the solution can result in the fine debris particles settling on the horizontal surfaces of the object been plated. This leads to a rough finish. Their answer is to place the anode in a bag to retain the fines like a dust filter does with air. I do not know what material the bag is made from industrially but my guess would be to use any very fine woven synthetic cloth. With the dust retained you would be able to use more severe agitation to help knock those bubbles off.
