not sure if this should go in this forum or the lights forum. well any way i up graded my t-5 lights about 4 months ago from cheap bulbs to AIT high output. and the colors are great but my mushrooms are all very small or gone. i had put what i had left in dark spots in the tank. how much light is to much for mushrooms or might their be something else going wrong? my tank is a 75gallon with 6 t5 54 watt bulbs. any thoughts?????????
