Morning guys, I know arcos and montis need different care requirements but I have a current usa marine orbit LED, it's on low to compensate for my chalice (20% W, and 90% on the rest of the colors) although my chalice hasn't been liking me because I'm getting more into the advanced aspects of chem so I've been changing stuff since I understand it now, so it might just be put in the shade for a while and let him grow back. Anyways, not talking about LPS, this is SPS. Would you think I have a chance at keeping arcos and other SPS with similar care requirements? Also what would you recommend for flow? I have a current usa 660 GPH (tank is 65 gal), blowing into the right of tank, I plan on getting another and putting it so it ends in the left side by my coral tower, my highest point other than my frag rack. Would you think I could keep arcos with those? I try to keep my water at low nutrient, 1-2 PPM for nitrates, and 1 PPM for phosphates.
