And to top it off I most defintly dont want to spend the hundreds if not thousands of dollars it would be to create enough flow in my new 210g tank with the vortechs. Overall I think this product has many cool features and looks cool in the box but has some heavy cons which outweigh the pros.

so what did you replace it with?
