It's more difficult than you might think, as I've found out.
I'm trying to hit 400+ PAR (the more, the better) on the sand bed in a 120x60x60cm (~4'x2'x2') system at a water depth of 40cm, for gigs and clams. So that's ~1500+ PAR nearer the surface. I have 2x spectra 400w halide systems that *might* do it. Maybe 4x Kessil a500s? I also have 4x GrassyCore LEDs I could mount perpendicular (~180 watts each) and could mount t5 retros on either side as well. I'm currently using ATI Stratons and I like them but they push about ~2xx PAR to the sand and ~6xx near the top, so just not strong enough (~400w total).
Really interested in the Geisemann Aurora (V8 or V12) but not sure if it'll be enough light or not.
Open to suggestions!
