A 45 gram CO2 bottle is not a worthwhile investment on such a large tank... you will never be able to maintain a consistently high CO2 level. IMO, they should only be used on nano tanks if a refillable canister is totally out of the question. I can't see that thing lasting on your tank for more than a week, and probably not even a day if higher CO2 levels were maintained.-Small 45 gram co2 bottle with bubble counter (about 1.5-2 bps)
I would recommend just using the two of the 65 watt bulbs, preferably the white ones, and discontinue use of the blue bulbs. More than 2 bulbs over your tank without proper CO2 injection may lead to algae issues. You can always add more white bulbs later down the road if needed.
Good start overall!
P.S. I see you're from Phoenix! Make sure to check out AAPE (Arizona Aquatic Plant Enthusiasts) if you haven't already.
