Hi, lovely tank, yes I’ve been battling with high Nitrates and phosphates from day one, mine have been up to 80 ppm just tested them today with, API and also with the Salifert testers. It’s 3 years now that I am in this hobby, my water like yours as always been clear even when doing a bi weekly change, longest a month and the water is as clear as the fresh mix I put in. My nitrite and Ammonia never been above 0, I’m puzzled because if I was over feeding my fish surely the ammonia would be above 0, could it be when I feed my corals, does that increase Nitrates! Also I rinse frozen food with RO water to reduce Nitrates, maybe I will do a bit of research into what coral foods don’t add Nitrates to my water. My corals on the majority are doing fine Lps slow growing but ok, my Zoa’s use to always disappear but now for the first time I’m having success, don’t know what’s changed but are growing and happy.
Now besides my Nitrates, phosphates have had readings as high as 20 ppm have no issues with any form of green algae on my rocks, they are clean and only have Caroline algae on them. I do get a little diatoms on my Caribsea Fiji sand bed, mainly at the front of my tank. I have just installed a phosphate reactor in my sump hoping that this would help, crossed fingers.
