OK here I am back. I am going to do away with my glass top. I have no life stock in aquarium to speak of just 1 green chromis and some hermits. I just want to keep the easy to deal with corals, low maintenance and a few fish in my 75. Currently have 2 48'' PC light strips with only 4x 65 watt total bulbs. My tank is still cycling as has only been up for almost 4 weeks so I am not to worried about getting corals any time soon. I know I need to replace the bulbs as I am sure they are older than 6 months and just wanted to get something instead of buying new bulbs for the PC. so I was thinking on getting a 4 bulb t5 fixture and using one of my PC strips that would be 2 x 65. Would this be enough to keep the easy to maintain corals.
