Product Questions

What is the depth range the skimmer needs to sit in? Alpha 300
Question by: Brian on Jul 29, 2016, 11:08 PM
Hi there,
The Vertex Alpha 300 can take a variety of water depths from 7 to 10 inches or so. Each system will be different in what makes the skimmer work the best, however if you have a depth in between 7-10” you should have no issues with that skimmer.

in the details says that the Footprint: 23½" x 18" or 24" x 16½" or 21" x 18"

is that mean that there are three deferent footprint sizes?

thank you
Question by: saoud on Apr 30, 2014, 6:42 AM
Hi Saoud,
Good question. The footprint will vary depending on how you decide to mount the pumps. Different orientations of the pump will end up with slightly different footprints.

Looking at this skimmer for a 400 gallon reef. Does it have to be placed in sump or can it be plumbed outside the sump?
Thanks, and love your site!!!
Question by: Robby on Apr 8, 2014, 6:52 PM
Hey Robby,
All of the current models Vertex skimmers would have to be placed in the sump. Skimmers that could be placed externally would be the "recirculating" skimmers (Vertex does not currently make any models like this). This would be a model that could be plumbed externally and would be large enough for your tank. Thanks for the kind words!
