GC Tek BioMotion BioVerter · fluidized-bed biological filter · 1.5 to 8 cu ft

Add biological capacity without adding a pump

A fluidized bed is the most efficient biological converter there is — media in constant motion, every surface scrubbed and fed, no dead spots. Most fluidized beds need gravity or a dedicated air supply to move the bed. The BioMotion doesn't: the flow from your existing filter system fluidizes it. The media is barely heavier than water, so it sinks when the flow stops and even a 1/8 HP pump's output is enough to raise and fluff the bed. Add one to a new GC Tek system at time of order, or drop it into an existing pond to raise biological carrying capacity when your fish load has outgrown the filter.

BioMotion media looks like the AlphaONE open-cell media but is black and sinking. Pair a BioMotion with a NishikigoiRDF drum or an AlphaONE and you have mechanical, biological and fluidized-bed conversion in one loop — GC Tek calls it the ultimate waste treatment system for a pond.

Ordering & delivery

How long until it ships?

Most GC Tek filters and systems are assembled to order in Chandler, Oklahoma. Typical lead time is about 3 weeks from order to ship, then transit time. Parts and media we stock ship from Upland, CA within a day or two.

Why no freight at checkout?

Freight for a pressure filter or pre-plumbed system depends on your address, liftgate needs and residential vs. commercial delivery. Charging a flat guess would overcharge some customers and undercharge others, so we quote it to the dollar and confirm with you before shipping.

Can I pick it up instead?

Yes — pick up free at Mystic Koi & Water Gardens in Upland, CA. Choose local pickup at checkout or tell us in the order notes and we'll skip freight entirely.

Who handles the warranty?

We do. As an authorized GC Tek dealer we process warranty and parts through the factory for you — no shipping the tank back across the country.
