As most of you know, I got myself the Vortex XL diatom filter a while back ago. It's been quite the lifesaver, and a definite workhorse. I've used it on my 75G for polishing, and on my 29G to help rid algae. And now in the 10G tank with 2 25W bulbs, I just could not get rid of the greenwater, so instead of doing a blackout, I went the route of my trusty diatom filter. Boy, what a change, lol. Water went from cloudy to crystal clear in less than 5 minutes, lol. Of course, the diatom filter runs at 450GPH, lol. Just so you all know, it works wonders even on the small planted tanks.
And no, it was not to powerful either. It was absolutely perfect.
