Is that right?
Well, there's a filtration method called the Berlin method that uses LR
and a skimmer. However, being that this is your first SW
tank and its only 10g, I wouldn't try to do that one quite yet. It'll be way too easy to overfeed and have your parameters go out of whack and have problems. I would do a hob
filter rated for 20-30g tanks. It'll help you in the long run, just clean it out every week with PWCs.
