I appreciate darts! lol!
Right now I'm i the process of drawing them somewhere else. They've got two buckets of sugar water with flowers floating in them covered with honey. They're thrilled. Very few are bothering the hot tub right now. So far not one bee has died in the buckets and that's not a bad thing.
I did put in spa cleaning solution and ran that yesterday. Drained the tub (again). Refilled it with fresh water (again), cleaned out the filter (again), added all the right chemicals (again) and extra clarifier. This morning the fountains have a bit of a trickle, so there's that.
I'm going to drill holes at the fountains dead end points, flush out the bodies, then plug the holes with rubber stops. I've needed a way to clean them out since I got the hot tub and this is the best solution that I can come up with right now.
Any more darts and I'll listen! lol!
