I have a frag that's prob 1inch square that's growing well but doesn't look healthy as I've seen others have it. edges are bit dark and has dark spots on it. I've been told low flow & light. I have moved it around but hasn't gotten better or worse. ... I've had water checked by local store and parameters are on point across the board. I have an aquaticlife fixture that has 2 (150w halides) & 4 t5. I keep t5 on 8 hrs and halides 4hrs. its been in shaded area for a little while now. ideas. ? thnx
