For some long time reefers have strived to maintain low nutrients levels. Spending hundreds if not thousands of dollars on mechanical, chemical and biological filtration in order to provide corals with a balance of nitrates and phosphates. Many have their own equations on what's best for sps corals. Some say 0 nitrates 0 phosphates, others say nitrates at 5 and phosphates at 0.03 for better coloration and growth. I have also heard anything above 0.03 phosphates and 0.5 nitrates will inhibit growth in corals. After Watching Sanjay talk about his 500 gallon reef tank and how he maintains his 50+ppm nitrates and 0.4 phosphates with little to no algae I was left speechless. It made me think how is it possible that he has many beautiful sps corals with such high nutrient levels with little to no coral browning ...all colorful and thriving, yet we sit here trying to tinker our nutrients to obtain the right balance... often killing our corals because we starve them to death.. Just wondering if you guys have any input on high nutrients and thriving corals like Sanjays.
