Ok, so my knowledge was very limited at the time
I was active on a small forum where more light=more pearling=great plants was a rule..
..so i decided to tune my 50lit tank from 1x15w t8 to 4x20w bulbs.
It pearled all right
Took about a month to distroy the plants lower leaves , got some BBA on the anubias.
Than i sold that tank ..
I wonder how it would look few month later with that light and diy co2
