I know that I'm not supposed to feed them until the water temps are higher (50F plus?) but we're going to get there this week. None of the pond plants are even peeking out yet and I don't want to feed them until the N cycle is in motion at least. So what to do? They are munching on algae but I do have some fall/spring food available but have not given any to them yet. Just worried how their waste will be processed if there is not much bacteria activity/plant growth to process it. Both our waterfall biofilter and the external Pondmax 3600 are up and running and I have seeded the pond with live bacteria from our pond shop day before. Any thoughts? It is forecast to go back to high 40s/low 50s for highs and 30s in the forecast till April 4th.
