What has happened recently? I know I haven't posted too much on the behind the scene changes. I was able to barrow a PAR meter and have set my tanks to 70PAR at the front glass substrate per Tom Barr's posts on FB. To quote, "this is much more forgiving." I went ahead and put all my tanks at these PAR values. So it's about 72 mid front and about 62 front corners. I also asked about the NBAT folks, Tom and a few others mention these values are probably similar to what they run. So why not try to mimic them?
