Anyone else have this problem?

I have added twice the recommended rate of Aquashade to my .62 acre pond and still I can see the bottom at five feet again (I haven't tried lately but I bet I can see my seechi dish on the bottom in 11 feet of water.)

Sago Pondsweed is going nuts down to about 5 feet and I even have some coming up in 8 feet of water.

Not sure about the Chara as I don't seen any on the bottom where i can see it but perhaps the Sago Pondweed is out competeing the Chara? I'm still not seeing any effect of the Hydrothol 191 on the Sago Pondweed. Plants look no different than they did two weeks ago.

What gives?

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