Overall the sq 520 shows a higher par on all tests but the biggest difference was under the halide not the led as I was expecting.

Update on fluconazole, don't hesitate on trying this as it works great I dosed 9 pills for 90 gallons for 14 days everything was left on for the most. (Skimmer was off for 2 days) don't think it hat needed to be.
