Pond Boss Forums MANAGING AN EXISTING POND Fertilization Fertilization with rain coming in?

Pinetar, what is your visibility now? (secchi disk reading)

You can make one if you don't have one from a white 5 gal bucket lid.

Don't forget that all the feed that you are feeding the fish is also fertilizer once it passes thru the fish........

With as good as a fishery that you have now, I would be very careful of changing anything for fear of screwing it up.
