Hi Michial
im using a similar setup
ike housing , p5000, 2x inon strobes fired by hotshoe.
inon uwl100 with dome attachment ,2x UCL-165 M67 macro lense and another on the way.
i have a few shots taken with this setup if you would like a look

i use the camera in manual mode.
metering center- weighted
AF area mode- manual
optimize image- more vivid
iso-100
auto focus mode- full time AF
VR - off
WB -flash
wide shooting apeture - 1/125-1/500 f about 4.3?
macro apeture 1/500 - 1/1000 f 7.6
i really like the dome attachment for the inon wide lense.
i also like th inon stacked macro lense UCL-165 M67
i have found the thread on the front port difficult to get correct while underwater so i select the lense for the dive and attach on land , turn the lense anticlockwise to seat the thread (you will feel it click in ) and then screw on.
batt life is a bit short so i just change batteries after each dive
best of luck with your setup
regards
matt
