Red sea reefer LED 90 help!

[Reef_Frank]

Hi all,

I'm having trouble keeping any type of sps coral alive, but I feel all my parameters are stable enough. Perhaps light intensity is the problem but I have no way to check this!
Can anyone with a nice healthy tank post their lighting intensity and schedule for the red sea reefer LED 90 so I can copy it?
Thanks in advance

Post a picture of your tank and what size tank? I have the RSR 200xl which isn't a big tank and I would use more than 1 reef led 90 on it for sps. I currently have 2 ai primes and 4 t5s over the tank

Its a red sea reefer 425 with two LED90s. Lights are on from 9am to 8pm with a max of 55% blue 35% white.
Without a PAR meter I'm never too sure what the intensity is!
Thanks for the reply

I have the same tank and lights. Although my frags are young they are all doing great. I use the stock 20k program and blues are at 100% and whites 50%. Here is the Red Sea par map for reference. I modified the photo to put them side by side. It looks like your frags may need to be raised up higher in the tank and/or increase the intensity…

Also double and triple check your salinity with various measuring devices. I recently had a refractometer that I calibrated but was still inaccurate! I used a Hanna salinity tester and it was only at 31ppt. Slowly increased to 35ppt and corals look much better!

Awesome thanks for this, will gradually change towards that setting and see what happens! Definitely seems like my intensity was too low
