I have set up a 90 Gallon tank with stand and canopy, Pro clear aquatics pro 150 sump with skimmer, Gamma UV sterilizer, and Aqua logic Chiller. For lighting I have Nova Extreme Pro 8x54 t5 fixture, What should I use for media, 2 Chemi pures?, Or one bag for carbon and one bag for phosguard? Suggestions please. :wavey:
