You said "they're not actually 0 because my chaeto is growing well"... guess what is taking up your nitrates and phosphates and causing them to bottom out? If they're not "really 0", what are they? Giving false numbers won't help your cause here. I could be wrong, but your whole approach and provinding of information here seems to be wrong. What kind of Hanna checker are you using? HR? If so, that's why it's probably not able to detect it properly for you. If I am not mistaken green and red also cause algae growth like crazy (therefore should be kept at a minimum), but they should not be 0, but I could be wrong on this one.I actually tried to grow that algae for a tang and to not get dinos. So when I stopped dosing nitrate and Phos, it went away on its own. The reason I say they are not truly 0 is cos I have a refugium with chaeto and it is growing well. I also have zoas that are growing really well. So I dont think it is true 0. It just dont show up on tests. Even when I was dosing, it rarely showed up on test kits. I used both Hanna and redsea. Only battle with algae is CUC and manual removal. This time I didnt even do that. CUC took care of it.
I have 2 kessil A360x for lighting. I increased the photo period since I got the torch by an hour to 7 hours. with 2 hour ramp up and 2 hour ramp down. Color specs, I think 0 green or red, there is 70 UV, and rest is all mostly blue. I have a PAR meter so I usually dial in based on the coral req and acclimate them over 2 to 4 weeks.
