Sps par readings?

tom obrecht · 03/22/2020, 03:41 PM

I have an 8 month old reef that I started over from scratch. And when I started over I mean new display, new rock, new lights, new calcium reactor and other toys. I have run halides over all my previous setups for some 20 years. I decided I would run Radion X15’s this time around. My question is what par readings are sps ers running these days? I recently did some par readings of 200-250 in the majority of the display but am wondering if that is on the minimal side? I ran 250 watt halides plus either reefbrites or T5’s on previous setups. Anyone want to chime in on their “successful” ranges?

No one wants to give their par ranges?

BRS have some very good video on the subject.

I use three X15s over 36x30x16 (75g). I have the Radions toned down to get 200-250 par at the level where the majority of my SPSs are, in which is about 2/3 of the way from the bottom up. Ever since I focused on what's going on with my par my corals have been doing much better.

Great thank you! I have watched the BRS videos and have taken the info to heart. I have seen various displays with everything from 175ish to 600/700 ranges. I’m currently around the 250 mark but may add a bit more once the system starts to take off. I use to run 250 watt halides with reefbrites and the corals did great! Now with leds I’m debating whether I have enough or not. Bad thing is I never took par readings with the halides over the tank. Wish I had to compare.
