How does a scrubber compare to a Remote DSB (RDSB)?
RDSB’s removes Ammonia, Nitrite and Nitrate. Scrubbers remove the same, in addition to phosphate, metals and CO2. RDSB’s, however, just like regular DBS’s, tend to store phosphate in the sand during high-nutrient times. It then releases the phosphate during low-nutrient times. Scrubbers don’t “store” phosphate; the phosphate is “in” the algae that grows, and it is then removed during weekly cleaning.
