I had made the assumption that I should run my waterfalls daily in order to flush them and make sure algae can't get a foothold. Now I'm wondering if I should do that at all. Seems like maybe it is pushing any algae I might have into my pool on a daily basis and providing nice, oxygen rich water to feed it (if it is indeed in there).
What do folks normally recommend? Flush daily or not? At the start of the day or end of the day?
