You should send an e-mail to the folks at Feller Stone before you take it out. It could very well be a manufactured item and not natural lava rock. I would hate to see you waste your hard earned $$ on something you could have used.
So if I have a good skimmer I won't have any problem with hair algae or cynao on the LR? (too many nutrients...?)
In a newly set up tank, both of these algaes (including diatoms) can be part and parcel of the nuisance blooms new tanks often incur. I cannot guarantee it won't happen but with a good amount of rock for biofiltration, a good means of export, not overstocking or overfeeding, you will at the very least greatly reduce the chances of this happening.
What makes you say skip the power filter, if I may ask.
Mechanical filtration works, it's just more hassle than it's worth when it comes to SW
aquaria. You will need to spend a weekly amount of time on it's cleanliness and will often be a source of nutrient itself if not maintained correctly. If you already had one I'd say hook it up for extra flow and possible the occassional resin/carbon product if the need arises. You can really do without it though.
Consider crabs, worms, pods
and snails your mechanical filtration "so to speak"
