Drained and refilled the pool about a month ago and realized yesterday I hadn't run the fountains since I refilled. The fountains are attached to an old pool pump that (as far as I can tell) does not pass through the pool filter. The pump basket is bright green with algae. Any tips on how to handle this situation properly with least likelihood of throwing off the rest of the pool chemistry? Was thinking just raise the pool FC to the high end of my range, clean the pump reservoir with bleach as best as I can, fill with clean water to prime and cross my fingers as I turn it on.
