Can I keep my lights at only actinic?

So I have the kessil a80 tuna blue along with the fluv 13 stock light. Can I run the kessil on close to if not pure blue and the stock light on blue and still get coral growth and same par?

If it’s LPS or softies then it should be ok, they are less demanding on spectrum. SPS could struggle without a full spectrum.

It’s only lps and softies at the moment, I plan to get sps soon
