Have you used the par meter to see what you're reading at various depths and locations?
Nah I heard the par meter doesnt really work with kessils. Something about their special dense matrix led gives you an un true reading.
Plus my corals are telling me about light intensity by dying lol
I've read the same thing but I think it's readings are consistently inconsistent. So if it reads 10% (just a made up value) less than what it actually is then you can count on this everywhere you take a reading with it.
I'm also not entirely sure where this idea originated from either though. In order to verify that the par values that are read are low you would need a par meter that could actually read it correctly to make that statement.
