75 Gallon Lighting

Tank Specs:
75g
250 Watts of heating
2 Penguin Biowheel 170s

Im putting together a DIY canopy for my 75g. that I am looking to plant. I have 3 4' two-bulb strips adn the bulbs I have to place in them are:
2 GE T12 40 Watt Sunshine
-2250 Lumens
-5000k
-90 CRI
2 Sylvania T12 40 Watt Daylight
-3000 Lumens
-6500k
-80 CRI I believe
2 Sylvania Cool White Plus T12 40 Watt
-3000 Lumens
-4100k
-70 CRI


My questions are IS this a Good Setup, I have 3.2 Watts per a gallon. But is the Kelvin, Lumens and CRI good? Also the substrate I will have will be Schultz Soil Condtioner and a Layer of Flourite underneath. I will be feritlizing with flourish. Is there anything else I should add? I was thinking about Co2 but I dont have the money to buy a whole setup right now so I was wondering if I did 2 DIY bottles of Co2 and inserted the one tube into each intake of my Biowheels if that would be sufficient? Any additional reccomendations would be highly appreciated.
Thanks, Ryan

Yes i found this out today, I have been readinmg up a lot and figures that I need to buy some more stuff such as a pressurized co2 system, some bulk fertilizers as using flourih for this tank would be very expensive and some better reflectors for my lights. Im also going to get 2 mark v sponge filters for my tank instead of the biowheels. I have also changed my substrate to a layer of mulm and gravel then a layer of laterite then a layer of the soil conditioner
