For traces: add 30mls SeaChem Flourish.
Also, you do not indicate if you add GH booster etc or not nor what the GH is.

You'll need to get a handle on that also.
Adding 2 teaspoon after a water change will resolve anything there for GH.

The rest is CO2, cleaning and maintenance.
You may consider bombing with Excel in addition to cleaning, trimming, and blackout for 3 days+ 50% daily water changes.

That will knock any species of algae way back.

More light means more growth and more dosing and more mainteanace
Careful what you wish for there.............

There's nothing you cannot grow with 2/w a gallon of PC lighting.
It just will grow a bit slower and ultimately be more manageable.

High light tends to be for mid level/intermediate aquarist that do not listen or just figured more was better if they are a newbie, the pros and experts use less.

If you do decide to upgrade, go with T5 lighting at about (assuming the tank is 48" L) 54w x 6.

This is a lot of light, and if you space it over the entire top, not all bunched up, this will make the tank look nicers also, same with the 4x 65w, if you can angle them out away from eachother more that's best.

Note, 4x 54 w is plenty of light for most applications for this tank size.

But with the 6, you can stagger the lighting, do 2, 2, 2, one then 2, off, 2 off and all off for a 1- hour high noon effect with each light being on for 6 hours etc of some combo close thereof.

Or you can do the 7 hours of the front 65x 2 and 7 hours of the rear 2X65w with a 4 hour overlap.
