Tank Specs: ADA aquasoil+Power Sand, 8 in depth from surface to substrate
Any help is appreciated!
I think both fixtures come with mounts that raise them 2" from the surface of the tank, so you're looking at a depth of about 10" from light to substrate. You'll definitely be in the high light range with the 18" Ray 2 (around 100 PAR). The 20" Fugeray will give you about 60-ish PAR, which is on the lower end of the high light range.
