I found an article by Bob Lusk on chara, and water ph. apparently chara will not grow in water with lower ph, at what point it doesn't say.
Mike, have you checked the ph of your water, and would it be possible to lower your ph without damaging your pond, or costing alot of money.
Cecil said because of the water exchange rate in his ponds treatment would be prohibitive, but It looks like you don't have a big water exchange.
