Depends. If the tree is NOT dead above the graft, and you want to keep the variety, cut off that root stock growth, otherwise it will overwhelm the variety. Rootstocks are rarely good fruit producers as they are bred for vigor and cold/disease resistance, etc., not for fruit.
If the top of the tree is dead or you want to graft on a new variety, you can simply let that root stock grow for now and graft it right before it breaks dormancy in the spring. It’s very easy to graft.

The only way it will go “un-anaerobic” is if you decide to aerate it somehow. Though when you water with it, air gets mixed in, so it probably doesn’t matter.

I don’t worry about it going anaerobic – the nutrients are still there. It’s a great fertilizer.
