It has about 99% likelihood of algae issues,
It's simply bad management to add a high light system to a non CO2 slow growing plant set up. Exceptions? Sure, and very very few of them.
If you have a lot of floating plants, eg, a mat of water sprite, then sure.
Emergent plants mostly?
But most do not want that.
Crypts and Anubias?
High light and no CO2?
And no algae?
Try this underwater, let me know how it well it worked out.
If you put 2x 24W T 5's on a 20 Gallon tank, and try this.....I'll take bets on this one.
