Currently run 2 of them, the tanks 48x18x16. I get shadowing an stuff so I’m adding another 2, anyone have any idea more or less how intense I should have the lights since I’m doubling the amount? I posted my current settings, was wondering if anyone has an idea what intensity will give me what sort of par. I’m mainly keeping lps and nems. Might get rid of the nems though and add them to my nano
