Hi everyone, I’m in the situation that I have a diy led light 8000lumens 6500k plus 10w full spectrum led and I dose the EI standard dose calculated via rotala butterfly website but I noticed some deficiency and when I tested the water I found out that I have N 2.5 P0.25 and unknown K , Fe 0 co2 30ppm .Is this possible because I have to much light ?
