I have a 2 foot deep tank , my lights are hanging about 10 inches off the surface ,
best way I found to acclimate corals is start out with just the blues on the lowest setting raising them slightly over a few days once you find the spot you like your blues turn on whites on lowest setting leaving your blues where there at and repeat with the whites watch how your corals react over a week or so as you slowly raise them ,
my coral seems to like around 20% white 60% blue but I keep softies and lps
only , sps
watch your corals they will tell you what they like .
take it slow and watch how things react , watch if they are opening up full or if they are unhappy not opening and trying to hide or just not fully open ,
it took me around a month to dial them in perfect fiddling with both whites and blue
don't rush trying to get them adjusted because too fast can shock your corals or even bleach them . remember every tank is set up different so don't follow someone else's settings as there corals are placed in different spots and layouts are different also depths of tanks vary , go slow take your time once you find that perfect spot you'll know it ,
