I have a 6 month old Red Sea Reefer 250 that I am stocking up as a mixed reef tank with fish. Soft coral dominant, but do want some SPS and/or LPS in the future. I am a long term freshwater fish keeper (40 years) but new to the saltwater hobby so are sticking to the beginner options. Currently have a couple of leathers, a torch and and some zoanthids.

My light is a Maxspect Razr 420R with the marine clusters. I am currently running a cycle maxing at 50%. I don’t currently have anything to measure PAR however. The tank is 18” (45 cm) deep.

1. 07:00 A 0%, B 1%
2. 09:00 A 15%, B 30%
3. 12:00 A 50%, B 50%
4. 18:00 A 50%, B 50%
5. 20:00 A 30%, B 40%
6. 22:00 A 0%, B 1%

Does anyone have any experience with this light in a tank of this depth?
Any suggestions as to the light cycle and max %age I should aim for?

Currently the corals are going reasonably well. The Sinularia and the brain coral are very happy, the torch seems ok, but one set of Zooanthids died, and some of the second set also died. The others seem ok for now. The zooanthids were placed lower than the other corals.

Thanks!
