Thanks for your reply Jeff, the pond is about 10 yrs. old and usually has a good bloom and hasn't had any FA or other algae in several years. The pond is fed by underwater streams and only has between 10 and 20 acres of water shed. I do not live there and it is not unusual for me to miss 2 or 3 weeks going up there. That is not my choice but I have health issues and still try to work during the week so it would be hit or miss on testing. I don't have elec. there yet but hope to this year. Thanks again, ken.
