If you think the nitrates are too high- do a PWC
. Couldn't hurt anyway. I feed 2-4 times a day, as much as the fish and corals will consume in less than 5 min. You' should see positive growth in all your animals in the tank, and little to no algea growth. You could add a little more to feeding, and if you get algae, then cut back. Fish aren't growing fast enough? Add some more. It'l take a few weeks to find the "right" amount and time slots to feed. But then you'll find what works perfectly for your tank and will be able to feed perfectly.
