Well, I finally got ball valves! They're glued on and the skimmer is "simmering"!! Couldn't be happier, it's been a long haul. PM said it would take 24-48 hours for the skimmer to "break-in", sooooo it's properly simmering. From the base to the top it is loaded with bubbles..never saw such beauty

Just very happy-no leaks---so far, at least this time around, although I did have to cut off elbows and redo the dang thing as I hadn't fully thought out the added length the ball valves and already had glued the whole thing together

But right now things are looking much, much better and I finally feel the filtering system is good enough for the tank!

to you all, I received a lot of help along the way and am very grateful. Next,

!!!
