The distinctive curved 'Beer Bottle' body of IceCap's K1 skimmer line isn't just styling - the shape is built to disperse bubbles more evenly through the reaction chamber for better foam fractionation. Five sizes span nano tanks up to 140 gallons.
Why the Beer Bottle Shape
A curved body changes how rising bubbles distribute through the water column compared to a straight cylindrical chamber, giving the K1 line better contact time and foam quality across its whole size range - not just a styling choice.
Choosing a Size
- K1 NEO - the smallest skimmer in the K1 line, built for 5-15 gallon nano tanks and the back overflow chambers of small all-in-one setups.
- K1 Nano - steps up from the NEO for tanks up to 30 gallons, with an included magnet mount rated for glass or acrylic.
- K1-50 - built for in-sump installation on tanks up to 80 gallons, with the same distinctive curved body.
- K1-100 - built for tanks from 40 to 80 gallons, sharing the same bubble-dispersing chamber design as the rest of the line.
- K1-130 - the largest in the K1 line, rated for 80 to 140 gallons, sharing the EVair 400 pump and curved body with the smaller sizes.
Setup Tips
- Break in gradually - new skimmers commonly overflow with microbubbles for the first 1-2 weeks until they season.
- Check your sump or nano compartment depth against the specific model's water level requirements before ordering.
- Empty the collection cup regularly rather than letting skimmate sit and potentially drain back into the tank.
