I have a panworld return pump that'll do you. Lemme check the model number when I get home but I think its a 100pxx (1300gph circ). I also have a few spare tanks, tho not a 20high. I have 20l, 29 and 30. I also have a skimmer that would be perfect for a 150, but its a tall Beckett. Not something that would fit under.
