I had a reef fixure over my 54g corner tank with 4 t5ho 10'000k actinics and a 150w mh 10,000k. I had no algae.(the fixure was about 16" over the tank.

I now have 2 6700k bulbs over my 72g and I have tons of algae

algae is a simple organism.. it will use light the same as plants. blue light Penetrates further and thus will give you more usuable PAR at depth so that can be a cause of algae compared to other bulbs. but adjusting lighting levels, co2, or photoperiod can handle the difference

and to expound upon my earlier statement. I would START by not using the actinic bulbs. just the 2 10k and see what happens. lowering ur light level will reduce the need of nutrients to for the plants, this includes co2 which is the major nutrient as far as plant growth is concered.

u can also keep the lights and adjust by increasing c02. its a lot more tricky to handle and get right than just reducing light, which does reduce the need for co2 itself

Thanks for the help - I purchased new bulbs today. We'll see how it goes tomorrow, I also turned off the actinic bulbs for the day today and just used the other ones.

I also did a major cleaning of the tank and got a ton of the algae out. Hopefully if it comes back it will be less virulent.

Amanos and dwarf shrimp largely avoid this type of algae. If you see them on the algae, they are mostly grazing upon it and not actually eating it.
