Agreed, get rid of the actinics, get two bulbs with 6500k rating this will even out your spectrum and give the plants a better chance at growing strong.
In addition the DIY CO2 is not really recommended for a tank that size. I have a 90g with pressurised and it pumps out heaps of CO2 just to keep the PH at 6.8. I don't think that a DIY unit will even come close to maintaining your PH. Worth considering investing. Not only this, but the plants will be starved for CO2 and will not grow as quick, which in turn means that algae can take a hold. Which it has clearly done.
Take my recommendation get the CO2, and you will be selling plants back to the LFS before you know it. That will help to make up the cost.
BTW I think aquabotanic sells CO2 gear for quite cheap. Pity they are not located in Australia.
