Jeremy what do you recommend for a good starting point onthe alpha 200 ?
1. water depth (right now @ 10")
2. water inlet/venturi adjustment (right now @ 1.5 turns)
3. wedge pipe (right now @ 60% closed)
You have the right pump. I have been seeing sites show the 1500 but the correct pump for the 170 is the 1000, same block as the 1500 just tuned down with the pinwheel and ventura. I have a 170 with the 1000 and it is the correct pump.
OneReef - you do have the correct pump.
I would raise the water level up with the pipe a couple of inches. If your skimmer is new it could still be breaking in. I have the 170 and it just gets better with time. Do not make too many adjustments without letting it go a few days in-between.
The only upgrade for the Alpha 200 was the adjustable venturi.
Which port are you talking about, the small grey ozone port?
