IceCap K1-Nano Protein Skimmer

The IceCap K1 Nano is a remarkably compact skimmer that offers a new level of refined filtration. All aspects of the skimmer were implemented to surpass many challenges other skimmer on the market miss out on. Included magnet mount allows for easy placement on surfaced up to 1/2" thick.

It is compact and built to last, crafted from robust PVC and high quality acrylic. All components are marine safe and refined in every aspect to provide the latest enhancements in foam fractionation and the highest in quality.

An impressively compact footprint makes it the ideal candidate for tight compartment applications. Every aspect of the skimmer disassembles completely for easy service.

At the Core of the IceCap K1, you will find the DCair 200 skimmer pump built to provide efficient performance.

The pipeless output offers fine-tuning and trouble free underwater outflow plus quiet operation. Our pipeless design not only saves on space but also allows the outgoing water to exit on the side of the skimmer and below the water surface providing splash-free circulation in the sump.

Love this skimmer

Pros: Works great And price is on point

Cons: A little noisy

I was skeptical of this cute little skimmer. It’s pretty much almost plug and play. Only a few items need to be attached out of the box. But once plugged in it works like a charm. Heads up - it does give micro bubbles at first, but they go away after about 2 days. Within 12 hours of putting this little guy in my tank I had a full skim cup (and it was gross) . I’m shocked how well this cute little skimmer works. The only down fall is the noise level. Maybe it’s me and I had been out of the hobby to long, but this little skimmer can be a little loud. Have to get used to the sound.

Good but not at first...

Pros: Skims great

Cons: could be noisy

Purchasing this skimmer was an interesting experience for me. When it first arrived it was incredibly noisy. After working with Coralvue they replaced the silencer and the pump. Doing that fixed the issues and it's now skimming very well. It appears these are common issues with the Icecap, but it's easy enough to get it figured out if you have the patience to work with the manufacturer. It skims amazingly though.

Cannot use

I cannot comment on the protein skimmer itself as I’ve had it for almost a month now and I’m not able to use it because I received it broken. The day I receive the skimmer I opened it I saw it was broken I emailed Marine Depot and I have heard absolutely nothing back. Marine Depot has horrible customer service and I would highly recommend not purchasing items from this company it will be my last purchase From this company and have been extremely patient with them and sent them multiple emails with no response in return.

Cons: Pump went out after 5 months

This is a good little skimmer for my IM 25 only 3 stars because the pump went out pretty quick (5 months).

Good value skimmer for nano

Pros: Good skimmer for AIO tanks, hang-ons, or limited space.

This skimmer works in me IM 25 without any alterations. It sits in the chamber next to one of the surface skimmers and does need some break in and tuning to get right. I've had it for about 8 months and still going strong after a couple of deep cleanings

Great skimmer for 30g or less!

Pros: Price, quiet, effective, no microbubbles

Cons: NONE

I recently put this skimmer in my IM30L and have had nothing but great things happen since! It drops right into the second chamber and begins skimming almost immediately. Highly recommended a break-in period as with any skimmer running it fully open to allow the pump and skimmer to be utilized effectively and then tuning it after those two weeks. After about a week, it was already producing dark skimmate, noticeable effect on pH increase as well as nutrient reduction. This little skimmer has done excellent on my 30 gallon tank, and I’d recommended it on any tank up to 30 gallons. The skimmer itself is very quiet and produces no microbubbles into the tank. Tank seems cleaner, coral and fish seem ever happier! What more can you ask for?

Great skimmer

Pros: Skims really well. Super quiet. Very compact. Very strong magnet for holding it in place. Can easily make adjustments without overflowing cup. No micro bubbles escape back into the tank

Cons: Not really a con but could have been labeled a little better. The skimmer itself is labeled correctly but when adding the magnetic holder it increases the size to 4.25 inches. Luckily I could turn it sideways in the back of my all in one to accommodate the size

Great skimmer for a nano tank. Really pulls out a lot of junk in the tank. Can't even hear it run once I plugged the largest hole in the silencer. (The silencer on these have lots of small holes and one really large one, I discovered that holding my finger over the largest made it virtually silent, so I used a rubber stopper to plug it but left all the smaller ones open)
This skimmer makes a ton of micro bubbles inside and keeps them there instead of letting them back into the tank!
