Corals Dying PLEASE HELP

[VintageReefer]

And i think i might of figured it out not 100 percent sure but you guys Tell me what you think …. I ordered a par meter …. Par was extremely low in sand bed like 30 on top rocks like 60 70 ….

Not only was running radeons lights at 40 % but they where way to high i drop them down to about 16 inch from the top of the tank …. Tank tall is 28 inches …. I brought them down increase the power on the Radeon's … now im getting par in sand bed aroun 80 90 ….. 100 depend on the area and on top rock 150 170 180 …. What do you guys think….

Yes just what I suspected. Those prior settings were too low for those lights

Try increasing more, gradually to get 100-125 on sand, and somewhere around 250 on top of rocks

Your new par readings are much much better, but now a tad low instead of drastically low

You’re very close and could leave them this way but if you wanted sps up top you would need to go a little higher.

If keeping softie and lps only, then leave them as is and you should be good

Radions XR15w G6 Pro

XR15 lights are very weak par. I run mine at 100% intensity on AB plus setting and corals thrive. My tank is 36x22x22.

Yeah same issue here.. I have to run mine at 75% to get ~150 at sand and ~250 at top of rocks.
