Product Manuals & Documentation

AquaMaxx ConeS In-Sump Protein Skimmer

AquaMaxx ConeS Series In-Sump Protein Skimmers efficiently remove organic waste from aquarium water. With an advance bubble chamber design that features numerous conical diffusers, the turbulence in the reaction chamber is reduced and a stable laminar flow is achieved to maximize efficiency and performance.

Achieve a stable laminar flow and maximize efficiency!

In conjunction with the innovative bubble chamber, a powerful needle wheel pump generates optimally-sized air bubbles that force protein, waste and other materials through the hybrid cone body and into a collection cup for easy removal. The AquaMaxx ConeS Series is rated for aquariums 175-500 gallons yet are small enough to be concealed in a sump underneath your aquarium.

Computer-precision engineered and outfit with the latest filtration technology, AquaMaxx protein skimmers are engineered to deliver the performance and value you are looking for in a skimmer.

AquaMaxx ConeS Series Skimmers are built using a brilliantly polished cell-cast acrylic. They incorporate the high-end features hardcore hobbyists demand at a price everyone can afford. The ConeS Series is equipped with advanced bubble chambers, hybrid-cone bodies, air silencers and needle wheel impellers for maximum performance, efficiency and whisper quiet operation. They also have compact footprints to make installation as easy as possible.

AquaMaxx ConeS Skimmers feature custom Italian-made Sicce pumps with special needle wheel impellers to whip up large amounts of air with optimum bubble size. These pump and protein skimmer combinations deliver unprecedented performance and reliability. Aquarium waste will be vigorously removed from your tank so you can focus less on maintenance and more on enjoying your piece of the reef.

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.

Comments: Was already shocked by the cone 2, cone 3 but this is even more impressive. The effluent is way more concentrated near black. And the related performance is a steal for the money. I use it on an 180 reef. Some of the fish are almost 15 years old. This new design is no hype

Comments: the skimmer works exactly as advertised, and is very easy to set up and get going quickly my only negative is that when you twist the cup at the top to clean every couple days the pump which is attached by a small rubber hose disconnects and is a pain to reconnect other than that, i really like how well it works

Comments: This skimmer is amazing (CO-3) !!! Short of paying $1400 for a vertex alpha, this is the best skimmer I have ever used. The sicce pump is dead silent, which was must for the wife. It produces the most fine bubbles ever and for such a large skimmer, the footprint is surprisingly small. Skimmer is very easy to take apart and maintenance, huge plus. Could not be happier with this purchase

Comments: I previously had a Deltec APF600 on my 180 plus 50 gallons in the sump. That skimmer did great but this one seems to be pulling out more faster than my old one. Very quiet. I also run a CO2 scrubber on my skimmer inlet and was getting to about 8.07 daily with my old skimmer. Within two days, i'm now getting up to about 8.14 or so. Seems to me i'm getting quite a bit more air into the system. Not a huge fan of having the pump on the CO-2 off to the side but that being said it does save on height which helped me fit this into my cabinet.

Comments: I love my Aquamaxx Cones Co-1 protein skimmer so much that I ended up ordering the CO-3 yesterday for my office tank. All I got to say is this skimmer is top notch! Build quality is just WOW! Skimming like a true workhorse champ! Sicce pump is very quiet can't hear a DAMN thing and maximize efficiency too! This beast literally put my previous high end three times the price protein skimmer to shame! Can't wait to get my CO-3!!!

Comments: skimmer has been running for exactly 1 month now and all is well with no issues to speak of. It is still chugging along producing concentrated skimmate. Construction is top notch, polished and the shark 1.5 (sicce 2.0) is silent. The optimum operating level for me is 9.5 inches. I've tried it at 8 and above 10 inches and had mixed results. I highly recommend this skimmer to anyone looking for a solid, well designed mid-range skimmer. Dont be fooled by the lower air numbers. It's a performer.

Comments: This skimmer works great for its small size. I have it on a 120 gallon tank without any problems. I can't hear it at all. I would prefer if it had a bigger cup though.

Comments: Build quality is great, foot print if you have limited space in your sump is great. First I disassembled the skimmer, washed with warm water and vinegar rinsed well with warm water, put it back together. With in 30 minutes it was up and running perfect. If you don't have an ATO it will require you to adjust according to your water level, keeping it at 9 3/4 inches is perfect with no splashing and no further adjusting producing a fair amount of medium dry skim ate. This unit is almost silent no noise from the air intake and just about no noise from the pump. In all I'm very satisfied with this skimmer, crystal clear water, typical AquaMaxx quality and pricing. Thank you for quick delivery and easy ordering.
