hey Steve, how does it feel being single again? haha
the extra length does help as the bubbles have a longer period to rise and burst and the bubble trap seems to be doing a decent job - it is hard to tell for sure right now because my pump may be cavitating.
By the way...i removed the nozzle from the seaswirl - thanks for the advice there.
The frags are doing great, i added a MJ900 on the top left to get extra flow for now and they seem to like it.
