Hmm, i have a carpet for 6 months, under actinics, untill rescently Metal halides now . Hes done just fine, and is a beautifull anenomie, so i would bet it would do fine under power compacts. Todd
You only had him under it for six months. Long term he would have died. Also this guy has 60 watts of power compact. Carpets need metal halide for long term success. They like the substrate and power compacts can not penetrate the water deep enough to give them the needed lighting.
