Par question

[BigdaddyJ77]

I have a traditional 90 gallon long tank, and bought 2 kessil a160we's, can anyone tell me roughly what the par might be, if anyone might have this same setup, trying to see if I need to add a 3rd one or if these are good

How you have your aquascape setup can affect PAR readings, so a PAR meter will give you the most accurate results.

Ok thanks, I'll have to find a way to get one, I heard you can rent one
