I received my Vortex Diatom filter quickly and in good condition because it was packed well. With the free shipping and the 3Reef discount, this was the cheapest place I could buy it. I was also pleased that you had the accessories. I was able to add replacement impellors, get a large box of diatom powder, etc. (It's never convenient when an impellor goes out so I like spares). This was the first time I've ordered from Big Als but I'll do so again.
