Just wondering what are you Mn, Mo and Iron levels, maybe you are too low in these I have to dose all 3 in addition to ATI pro as my algae and corals seem to consume lots of them. Especially seeing you are not nutrient deprivedI do not how understand how my tank develops at the moment. If I only use my eyes on some corals - the answer is obvious - nutrient deficiency, the same with my chaeto and some very small patches of cyanobacteria. if I look at my measurements or some other corals - not a nutrient deficiency. My NO3 show around 4 ppm or less (using the high scale on Red Sea Pro says below 4 and using low scale - says 4 ppm. My PO4 shows everything between 0.30 to 0 ppm. The lower when I run my Al phosphorous absorbent. The funny thing is that I now add around 2 ppm NO3 on a daily basis - the NO3 readings does not rise !
The PO4 was nearly 0.3 in the morning 2 days ago. Two tests. Start the absorbent 7/24 and read 0 in the evening !. Add a very small amount of PO4 and read 0.03 yesterday morning. Today I read 0.05 ppm in the morning. I will add around 0.03 ppm during the afternoon and see whats happens. I have particles in my water - they can disturb the PO4 readings - but I do not know what disturb the NO3 readings - if anything disturb it. I have lover the flow through my reversed DSB. Will measure NO3 tomorrow. At the moment - I have stopped the H2O2 too - just a control thing.
Sincerely Lasse
