Hi, I have a 120 gallon mixed reef tank. I’ve had it up and running for about six months. I am relatively new to the hobby, but reading and researching everything I can. I perform an array of water tests, every week. One thing I’ve noticed consistently is that the tests show zero nitrate and zero phosphate. Yet, I have algae so I know this cannot be true. I’ve read that coral need low levels of both nitrate and phosphate for color/growth. I was previously dosing red seas no pox daily. I have recently stopped altogether. I’ve also begun feeding heavier. I’m curious, is there likely nitrate and phosphate in the tank that the algae absorbs faster then I can pick up on the tests? Also, if I continue to “dirty” the water will it just fuel the algae growth rather then make nutrients available to the coral? Thanx in advance for the help!
