My aquarium is a juwel rio 400 (400 litre - 100 US gallon) All my lighting is T5 - i have 2 x 54watt and 2 x 39 all with reflectors which apparently double the output of my lights, is this true? If this is true i have 3.7 watts per gal, if not i obviously have half of that (1.85 wpg). Do i need c02 with this lighting, if so i was thinking of getting the JBL proflora m602 system? i am dosing traces, micro - macro nutrients. Thanks!
