Just for the heck of it, I spot raked a few areas several weeks ago and it does work. In those areas, I now have sand; but geez, that's a lot of work, I'm too old for that; I didn't have a proper "pond rake", maybe it would be easier. That was some nasty NASTY stuff coming up while raking. Bill, I'm with you, I didn't have them on but I don't think it would be wise to run aeration while raking. Oh well, I guess I'll continue the chore, maybe I can get my 19 year old body back. A few weeks of raking should take care of 27 years.
