The IceCap K1 Nano is a compact filtration unit crafted from robust PVC and high-quality acrylic, designed for marine aquariums from 10 to 30 gallons. It mounts via a magnet bracket for placement alongside a sump or aquarium up to 1/2 inch thick and uses the energy-efficient DCair 200 pinwheel pump. (Note: IceCap's K1 Nano is sold as a protein skimmer; no separate K1-Nano media reactor exists in the manufacturer lineup.)

The questions our support inbox actually gets.
Does it ship quickly?+
Orders placed before 2 PM ET on a business day leave the same day. Tracking is emailed the moment the label prints.
What if it's the wrong fit for my tank?+

Who handles the warranty?+
We do. Everything carries the manufacturer's warranty and we run the claim for you — one email to us instead of a ticket queue.
How does the bundle discount work?+
Add items in the bundle builder: 2+ items saves 5%, 3+ saves 8%, 4+ saves 12%, and 5+ saves 15% off the whole system, applied at checkout.
