AquaMaxx ConeS Q-2 In-Sump Protein Skimmer Information

Product Manuals & Documentation

AquaMaxx has launched the brand new Q series of ConeS Protein Skimmers!

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!

AquaMaxx ConeS Skimmers feature high-quality Italian-made Sicce pumps. Each Sicce pump motor block is then modified and fitted with proprietary AquaMaxx needle wheel impellers. With the precise modifications and upgrades, performance is boosted much beyond that of a stock pump. The upgraded AquaMaxx ‘Shark’ pump is 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.

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.

  • Modified and upgraded Italian Sicce needle-wheel pump produces optimum bubble size for high-efficiency protein skimming
  • Cone body extends through the collection cup to easy bubble transition and maximize skimmer efficiency
  • Efficient, durable and reliable
  • Simple to set up and operate
  • Cell-cast acrylic construction
  • ShockMaxx rubber feet isolate noise and reduce vibration
  • New outlet design minimizes footprint, reduces skimmer height and allows for fine-tuning
  • Exclusive collection cup design with a handle that allows you to easy hold and transport the collection cup for cleaning
  • Filtration Rating: up to 250 Gallons (light bioload) or 130 Gallons (heavy bioload)
  • Footprint: 6.7" x 9.5"
  • Pump: AquaMaxx SHARK 2.0 (modified and upgraded Sicce pump)
  • Pump power consumption: 22 Watts
  • Chamber Diameter: 6"
  • Height: 19.3"
  • Recommended Water Level: 8"

Comments: I upgraded from the Q3 which is a fantastic skimmer but I have a super heavy bioload on a 300 gallon tank. I gave the Q5 a vinegar bath for 30 minutes and installed it in my sump. It began pulling stuff out within 30 min. This skimmer is a beast and also just as quiet as the Q3. I Waited several weeks for this to come back in stock and grabbed it as soon as It came back in. If you see the Q5 in stock and want it then buy it right away. sold out in two days. Im glad I held out for this one. Build quality is great for the price and Aquamaxx has great customer support also. make sure you measure your sump because it just barely fit in my Trigger Ruby Elite 36 sump.

Comments: Received skimmer with a seam leak and pump mount crack. Marine depot resolved the issue. I like this skimmer, works great but "would not buy again". The replacement pump is a slightly modified Sicce3 called the shark3 which will cost you a Hefty $200 to replace if u can even find one. Aquamaxx needs to come up with a modification mount so an inexpensive, readily available pump can be easily changed out with their skimmers or cut the price in half on their "sharks".

Comments: The only problem I've had with the skimmer is the pump's power chord insulation is breaking where it bends to go out through the skimmer body. And I haven't even had the skimmer more than a year.

Comments: Skimmer was shipped from Marine Depot quickly. Set up was easy. After running unit for a few hours in a vinegar bath into the sump it went. Took about five days for the skimmer to start producing skim mate. Working great now. I have it on a 93 gallon that's moderately stocked.

Comments: Cone SQ-2 replaced an air-pump driven, counter-current, cyclonic-flow skimmer on a 72 gal. ‘bow’ tank, with soft coral & fish. Quality construction-material used throughout, however; the black screw securing the ‘air silencer’ easily disconnects if bumped (screw should be a little bit longer). Set-up was easy, just followed the instructions regarding cleaning the skimmer before placing in sump). The Shark 2.0 pump created copious amounts of fine bubbles and; after some tinkering with the adjusting valve, ‘skim-mate’ production was occurring within hours of set-up. However, in order to operate properly the SQ-2 requires a constant water level of between 7 and 8 inches to sit in. If your sump isn’t baffled correctly, this will be a challenge (an ATO system may be necessary!). Skimmer running three weeks now and skim-mate production is great, however; I am having a problem with ‘micro-bubbles’ being carried along in the outflow water from the skimmer and finding their way into the main tank. I’m still working on solving this problem, but; overall I’m satisfied with this purchase.

Comments: Took me a bit to figure out why the skimmer was not making bubble. The air intake was actually clogged with glue from the factory, fixed with a like size drill bit. Air intake hoses kept coming off as well, a bit of cyanoacrylate gel on the sides fixed that. If wasn't for the oversight in manufacturing, would give five stars. Since then has been working like a champ, so much so that I have to turn off for an hour or so when feeding my corals.
