For all those curious I’m doing a review of the Fluval Marine reef 3.0 for a low tech light it’s pretty good, the app is decent although without a par meter you might find yourself lost adjusting the spectrums the light by itself will support softies however for any LPS and SPS corals I would strongly suggest extra lighting seems pretty durable has a excellent water resistant rating of IP67 so it could be submerged and still be fine, I would recomend having this light directly above the water using the mounting legs it gives you and unobstructed from water as this light is not the strongest but not the worst by the time you get to 18” the PAR reading is around 55 so water penetration is not the best, At 3": PAR=390, At 12": PAR=102 this will get the job done for softies the blue spectrum on this light is fantastic the app has a sunrise and sunset mode witch works great I would recomend this light to new hobbyists as it is easy and user friendly and can maintain softies and if you want to get in to LPS or SPS and anemones you will need to add lighting that about sums it up thanks for reading feel free to hit me with more questions! The pictures are corals I have maintained under this light and this light only.
