Hi all been a long time since Ive been here and a long time since Ive worked on my pond. Iam currently in the midst of putting my plumbing and filtration in, since I live in south Florida Iam figuring Ill be needing a UV filter to control the green water from the algae. Now what Iam wondering is what kind do I need. My pond is roughly about 780gallons, and the pump is a ES2500 which I believe does 2500GPH. Thanks in advance!
