For those with 20-Long and RAY2, how long is your photoperiod and is the finnex at stock height (on the glass) ? Thanks
I leave the lights on from 11am to 7pm red/white only. They sit 1 1/2" above my 20 longs versa top on the standard Finnex legs.
Here's what mine looks like atm. (Ignore my water level it needs a top up)
