Ok so i just recieved 2 oceanprop 15000lph pumps to play with and all i can say is WOW!!!
They are super powerful and exceptionally silent for the size, the suction cup mounting bracket attaches nicley and the pump is well balanced.
pre-programmed wave functions from a straight 5000 and 15000lph consistent flow to swapping from the 5000-15000lph on various wave sequences it also sports a night time mode where it shuts the pumps flow down to its lowest flow rate (5000lph) which is controlled by a light on the controller box sensor that reacts when to your tank lights go out.
Advantages
Silent/powerful/9-20w power consumption and controllable
Disadvantages
Large and takes up space but not as noticable be noticable in a bigger tank.
For smaller tanks i would be recomend they be concealed in an Overflow Closed Loop System (OCLS), i got these two to try and achieve this and will update on the outcome.
Other components:
In general:
My corals and fish loved it. The .65mm outlet really allows wide and gentle flow even on the highest flow setting.
Definatley worth the cash
