b-well just saw this post. ewest had good quesitons... What type fertilizer and how much did you use? ALso the question about top drain or siphon is useful. I think the rain flushed it out, may have been a blessing if you had 11 inches vis. Sounds like you have euglena and a red euglena bloom. THis is indicator of over fertilized ponds. If in metro ATL and you want a consultation let us know. thanks
