Product Manuals & Documentation

AquaMaxx Cone-Series In-Sump Protein Skimmer

AquaMaxx Cone-Series In-Sump Protein Skimmers efficiently remove organic waste from aquarium water. A powerful needle wheel pump generates optimally-sized air bubbles that force protein, waste and other materials into a collection cup for easy removal. The AquaMaxx Cone-Series is rated for aquariums up to 1000 gallons.

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 Cone-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 Cone-Series is equipped with bubble plates, 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 Cone-Series 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 Bubble plate decreases turbulence, improve bubble formation and boosts skimmer performance.

Comments: When I first got my AquaMaxx Come Skimmer it wanted to powerfully run wide open and it would completely overflow out of the top in less than one minute. I let it run that way (in sump) for a few days hoping it would break in and ease up but it never seemed to get any better. Eventually I cut the air hose and inserted an air control valve and dialed the air way down. This worked great for me. Now I have control over how the unit operates. It took about a month and a half though for those pesky micro bubbles to stop (mine had a ton of them) but now my skimmer works perfectly and I empty the cup about once a week. It is ALWAYS full of dark nasty stuff (yuk!). My 150 gallon marine tank is now crystal clear. Overall I give my AquaMaxx Skimmer an A+. After you go through the rough breaking period you'll be glad you bought one. I know I was!

Comments: I purchased this for my 75gal mixed reef tank with a 30 gallon sump. This thing is incredible! Started pulling skimmate out of the water almost instantly. My water is crystal clear now! High quality build/very durable skimmer so far. I highly recommend this skimmer for your tank. I bought it so that I can also use it on the 150gal tank I plan on upgrading to in the future since it's rated up to 300 gal.

Comments: This is an extremely powerful skimmer. In fact the smaller cone 2 is extremely powerful. The Cone 3 is very quiet and has no problems with large tanks. Have no doubt it can handle in excess of 350 gallons tanks. I use it on a 180 reef and the power draw is very small and nothing much to adjust. I did have a small problem initially seating the stand pipe insert. On the cone 2 it is solid but on this you need to make sure it is seated properly but very easy and one time inspection. A+++ skimmer

Comments: I upgraded my from my EV 240 which ran a mag drive 18 using 145 watts to this skimmer which pump uses 22 watts and must say the performance is just as good if not better! The main thing is that it uses 1/10 the electrical consumption which is always a concern in our power hungry tanks. It is lightweight yet durable and really plug and play. The adustment is so much easier and seems more stable than other skimmers I have had in the past. I highly reccomend this product.

Comments: I bought this after having another aquamaxx skimmer pump fail. They no longer made that pump so i was out of luck. So i stuck with aquamaxx because i really liked the previous one. So i have to say that right out of the box this thing is gorgeous! Put it in the sump and plugged it in!! The foam that this thing generates is crazy! Well designed, perfect footprint, and quiet as a mouse. Very happy i chose this skimmer my water is crystal clear and the next morning thecup was already almost full!! If u choose this skimmer u wont be dosappointed!!
