Q series protein skimmers easily fit in most space-limited installations and supply powerful filtration. Newly designed hybrid-cone body stabilizes and concentrates the organic rich foam as it rises! Micro-adjustable valve provides precise control, and allows cleaned water to exit the skimmer chamber at its base where it is less bubble.

AquaMaxx has a dedicated R&D team with more than 10 years experience designing high-performance, high-quality yet affordable protein skimmers. Moreover, AquaMaxx skimmers are engineered with computer-precision and are outfitted with the latest filtration innovations.

The new ConeS Q-Series protein skimmers are made with new and efficient bubble chambers similar to ones found on our popular ConeS CO-Series. The bubble plate in conjunction with the custom diffusers are designed to efficiently mix air and water. More importantly, random twirling and turbulent flow is eliminated. A stable laminar flow is created inside the skimmer`s reaction chamber and maximizes the efficiency of the skimmer like no other design!

High Performance

AquaMaxx ConeS DC Q-Series Skimmers feature high-quality Shark DC pumps. Each Shark DC pump motor block is fitted with a needle wheel impeller, capable of drawing in significantly more air and chops them up to the optimum bubble size for protein extraction. These pump and protein skimmer combinations deliver unprecedented performance and reliability. Accumulated protein and organics will be vigorously removed from your tank so you can focus less on maintenance and more on enjoying your piece of the reef.

Superior Design

AquaMaxx Cone-Series Protein Skimmers are designed from the ground up with the hobbyist in mind. A built-in air intake silencer reduces noise for near-silent operation. The hybrid-cone design maximizes the size of the reaction chamber and to allow the skimmate to smoothly rise into the collection cup. The advanced Bubble Chamber decreases turbulence and produced a stable laminar flow: which improves bubble transition and boosts skimmer performance.

    Yes, I would recommend this.

    Great skimmer - quiet..

    Pros: quiet and efficient

    Cons: i have none

    This has been hands down the best skimmer I have ever had. The build quality is great. Started skimming perfectly from the moment I plugged it in. With the pandemic I have been working from home. My tank is directly behind me and getting the noise levels to a minimum was a must. This skimmer is whisper quiet. The only thing I hear is a little air draw which is often the only way I know it is running. I for sure recommend this skimmer.

    I knew the AC Cones line of AquaMaxx skimmers were great. I was unsure if the DC pump systems would be just as good. I took the chance and am very happy I did. There were no reviews so it made it really hard to pull the trigger but I'll never us another type skimmer. At least I know this setup is very reliable. I choose this skimmer over OCTO. For the quality and price, this skimmer cannot be beat.
