Anyone ever dealt with this, or have more information on it? Kellie? Bill?

I could only turn up 6 pages in a search for this stuff and so far its in Lake Griffin in FL and saw a letter from the St. Paul MN area. Seems like some very nasty stuff, I only hope there is a safe way to eradicate it and that it doesn't get near my pond.

LD - you may have already found this commentary on that algal form. LINK

Cylindrospermopsis raciborski several years ago was called Anabaenopsis raciborski. A search using that name may provide more info.

I have seen Cylindrospermopsis in some local OH water supply reservoirs for about 4 or 5 years now. It always starts growing in August and decreases in September. So far it has not formed bloom conditions like those in other places. Florida waters have a lot of it. Lake Thunderbird Okla. had quite a bit of it last yr. Other reports of it come from So. NV, SE Idaho, most midwest states, Tenneesee, SE states, OK and TX. It is probably in many nutrient rich lakes / reservoirs east of Rocky Mountains.

To avoid introducing extra microscopic sized algae into a pond when adding fish I advise pondowners to never put someone else's water (inclucing hatchery water) into your pond. I advise to double or triple rinse stocker fish in buckets of your pond water before adding them to your pond. A friend does four rinses. Net out fish, and dip the net and fish into containers of your pond water, drain off water and then add fish to your pond using the net. Discard water into grass away from pond. I no longer dump fish and water directly into a pond. I don't trust what is in someone else's water. This is no guarantee the bad things won't get in your pond from another source but it greatly reduces the chances. An ounce of prevention is worth a pound of cure; providing a cure for this type of bad algae even exists.
