I just ordered the TF-100. In the meantime I’m using the Taylor K-1000. I also recently switched from tablets to liquid chlorine. Over the last couple of days our pool has been full of tiny black bugs (they look like small flies), also the skimmer was full of them. I’ve been cleaning the pool with the rake, but they keep coming up. I’m running the pump daily 5hrs on high and 3 on low. Any advice?
