Live Rock Rubble will do the SAME thing as Bio-Balls and is NOT a suitable replacement for BIO-BALLS in a Reef System! It's ALL gotta go!!

Nitrate (NO3) reduction is directly proportional to percentage of Water Change.
Allen's home-made formula...currentNO3-((%WC*.01)currentNO3)=finalNO3 (thanks Luukosian)
This means if you change 50% of your total water volume (That's EVERYTHING) you'll get a net reduction of (NO3) somewhere around 50%.

Ask me about how to increase your REEF budget without going without FOOD!!
