Calling live rock a weak denitrifier im sure is relative. Can macro algae remove nitrate much faster? Yes, given good conditions and sufficient mass it probably will. But it takes light and a certain amount of care (pruning, flipping if its not properly spinning, etc.) to keep it growing. I can throw several liters of siporax or a few marine pure blocks in my sump and have a really effective de-nitrification process. Evidence of this is abound in the sps forums.

If nitrate was the only excess nutrient in reef tank then denitrification would be all that is necessary to maintain reef tanks. Phosphate is a major nutrient in reef tanks, mostly due to food. Does phosphate resin complete the nutrient filtration team with denitrification for maintaining your tank? All corals need both nitrogen and phosphate to exist. Just like bacteria, snails, sponges and macro needs the same nutrients. Because I have shunned the stricter requirements of SPS, I have the luxury to allow the natural filter to correct. I choose to call that Dynamic Equilibrium.
