I have access to more cured live rock. Having 300+ lbs already, would I benefit from adding more (in refugium within the sump lets say)?
I recently learned about DSB effects/benefits. Having all this live rock, would I benefit from adding a DSB in a refugium (20 g Rubbermaid) within the sump or from adding more live rock? Tank has been established for about 3 yrs. Some small soft corals…about 7 total, plus blue tang, 2 percula clowns and rose anemone, mandarin goby, tiny snowflake eel and orange-shoulder tang. They have always gotten along fine…no bullies…all fish fed once a day (except eel which is fed 1 to twice a week). Also have clean up crew (about 50 blue and red hermits, turbo snails, etc.) 0 nitrites and ammonia, but nitrates have always been an issue until I recently got rid of all the bioballs, SLOWLY of course.
