ML,

I've never had Chara rise to the surface. Typical algae yes. If you can get it out I would remove it.

I just raked out most of the Chara from my trout pond. I have blisters on my hands to prove it. I would have gone inside to get the gloves but I was afraid I would be tempted stop and not complete the job.

And you know I just raked it out a month and a half ago!

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
