there is a thread about the dangers of using lava rock in salt tanks. you might want to check it out.
about the refugium- large particles will be pulled down the overflow and enter the sump. some people use a piece of sponge or filter sock to catch these, some don't. you can always vacuum the first chamber of the sump if you wish. unless of course, the overflows drain directly into the refugium. then i would suggest something easy to clean, to catch the larger waste particles before it hits the fuge. a filter sock will work fine for this purpose. i would also suggest cleaning out this membrane weekly, or even twice a week.
i use a filter sock directly after my overflows. i change it out about every three days for a clean one. if i wait much longer, it will clog. i toss them in the washing machine without soap (inside out) and they are ready to use immediately after.
i don't use carbon and my tank doesn't smell. maybe you are feeding too much?
No, my fish only get food if they take it from my hand....
