GC Tek UniClear · carbon polishing filter · removes tannin color
Clear water that still looks yellow? This is the fix.
Plenty of ponds are perfectly clear and the whites on the koi still look off-white. That's dissolved color — tannins — and no bead filter removes it. The UniClear runs high-grade carbon in a backwashable, lower-profile tank with a 2 HP agitator, absorbing the color while giving the water a final polish of fines. When the carbon stops pulling color, replace it. New for this generation: a larger carbon size and lateral assembly that stretch the interval between backwashes.
Pulls the color
High-grade activated carbon absorbs tannins so whites read white and reds pop.
Polishes too
Traps fines on the way through for the clearest water attainable.
Backwashable
Spring check valve and 2 HP media agitator included; carbon is replaceable.
Run it when you need it
Plumb with two 3-way valves and divert flow through it only when color builds — or run continuously.

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.
