JBL Solar Ultra

Anyone running these lights? I've read online that should I purchase, I should buy one Nature and one Tropic tube and run them together, as two Nature lights together will cause a mass algae bloom. Right now I'm just running the 2 stock 24W T5 lights (no reflectors) which came with my Eheim Proxima 175L tank, and I have no idea how these stack up against the JBL lights, or any other light for that matter. I have minimal algae right now but feel the plants could probably use a little more light. But on the other hand, I don't want to do myself in. Looking for some experiences with this product. Thanks!
