AquaC The revolutionary AquaC protein skimmers do not use venturis, downdraft tubes, or air pumps; they employ the patented "Spray Injection System." This innovation allows the protein skimmer to efficiently draw in much more air than any other of the top protein skimmers. This coupled with the superiorly designed compact reaction chamber yields results that will literally blow the waste out of your water.

How does Spray Injection Work?

In 1998, Jason Kim (owner and founder of AquaC) developed a patented process of protein skimming which has come to be known as Spray Injection. Unlike previous forms of skimming, our spray injection method enables huge amounts of air and water to be processed with a relatively small pump. Although it is a simple process, there is still some confusion as to how the spray injector works.

Imagine that you`re washing your car – you`ve got a bucket full of soapy water and a garden hose with a fast-moving stream of water. By placing your thumb over the end of the hose, you can disrupt the stream into a turbulent, high –pressure spray. Now direct that spray down into the bucket of water, and you`ll generate a massive amount of bubbles and air flow. That is exactly how our spray injector works.

The skimmer body acts as a water reservoir – the bucket in the example above. Water is pumped through the spray injector, which has a special nozzle that fans the water out into a pressurized spray. This spray shoots into the skimmer body, generating millions of tiny air bubbles. As the bubbles are formed, more air is sucked into the skimmer as a result of the local drop in pressure and the process continues.

Most other forms of protein skimming rely on special valves or media to generate the air flow, and these parts quickly become clogged with salt, dust, or even mineral deposits. The AquaC spray injector is a relatively large nozzle that resists clogging, and when combined with a pump prefilter, can be considered maintenance free.

The redesigned and improved EV Series skimmers raise AquaC`s spray injection skimming (U.S. Patent # 6,156,209, #6,436,295) to a new level in terms of efficiency, performance, and value. A new baffling system combined with a significantly larger mixing box results in far less turbulence and increased contact time. The net effect is a dramatic increase in skimmer performance despite a drop in pump pressure requirements. AquaC`s molded spray injector now generates a significantly larger number of microbubbles, boosting overall performance to unbelievable levels considering such low pump pressure requirements.

Features:
  • Flexible design for in-sump or external applications.
  • The new EV Series skimmers are designed to run in sumps WITHOUT BEING RAISED. The output gate valve has been increased to a height of 10" (EV-120/180 models), which means that as long as your sump level is 9" or lower you will not need to worry about fluctuations having an impact on skimming consistency. The powerful EV-120 can sit in water as deep as 9".
  • The addition of a precision ball valve for airflow control allows the aquarist to fine tune the skimmer`s output. Unlike most other high performance skimmers in this class, the EV is remarkably silent. The spray injection system does not generate the sucking noises typical of venturi and Beckett units.
  • The John Guest "Speedfit" fitting is a great feature you will only find on AquaC ozone-equipped skimmers. This fitting is standard on models EV-240 and above, and can be ordered on the EV-120/180. Aquarists may also connect their calcium reactor effluent line to the skimmer`s speedfit connection. The pH of a calcium reactor effluent typically falls between 6.5-6.9, and over time the addition of this low pH effluent can have a deleterious effect on the system`s pH level. By dosing your effluent directly into the skimmer, excess CO2 will be "blown off" into the atmosphere and the tank pH will remain unaffected.
  • The improved "Twist-Lock" collection cup and cap makes for a secure, flanged connection without the need for set screws or other locking type unions. Simply twist to crack the seal (EPDM gaskets) and removal requires a scant ¼" clearance. The new EV Series skimmers can be operated with AquaC`s auto-waste container, which are available in 2.5 and 5 liter sizes.
  • Increased contact time = more protein removal. The size of the mixing box has been increased on all models by approximately 40%. To accommodate the extra foam the skimmers now feature taller and wider reaction towers, as well.

AquaC Protein Skimmers in Use
This is one reef aquariums where the AquaC prototypes are tested on.

AquaC EV90

At the time of the picture, this aquarium had been running with an AquaC EV90. Note that this aquarium is fairly heavily stocked. After this picture was taken, quite a bit more livestock has been added to this aquarium. Currently, an AquaC EV150 is running on this well-overstocked tank. AquaC feels that this the EV150 is probably not neccessary for the tank, but they feed their tank quite aggressively to keep all the fishes that has been added healthy and wanted to keep maintenance at a minimum. According to AquaC, maintenance on this aquarium has been extremely low.

The AquaC EV-150 protein skimmer working on our aquairum:

AquaC EV150

Please note the dry consistency and quantity of the foam being collected by the AquaC protein skimmer. This drain cup is being filled on a daily basis. There is a convenient collection cup drain connector that allows you to drain the the waste collected in collection cup into a waste container.

This particular model stands only 20" tall, so it is extremely easy to place this skimmer underneath most aquarium stands. Even the model EV200 fits very easily under most aquarium stands.

REVIEW
I had this skimmer on my 140g for more than 10yrs(and it was used when I got it), and it worked quite well. The major pro for this skimmer is that it's as simplistic as you can get other than airstone skimmers. The only part that can fail is the feed pump which can be replaced by any aquarium pump o...Read More

Aqua C 120 skimmer

REVIEW
I bought this skimmer to use with a newly set up 75 gal intended as a reef tank. With new live sand and the contents of a 20 gal reef, it took just two weeks for significant skimmate to appear. I upgraded to the Mag 7 pump and only closed the outlet a small amount. the skimmer has been elevated a...Read More

REVIEW
Have been trying to use the skimmer for about a week. Would not produce enough bubbles to get skim. I ordered with Mag 5 pump but when I got it AquaC's manual with the unit it had been updated to say the 120 worked better with a Mag 7. So I am now trying to make a deal with MarineDepot to exchang...Read More

Great Skimmer

REVIEW
I bought this skimmer to run on my 55 gallon reef and I could not be more happy with it. The only reason i did not give it 5 star is because they say the mag 5 will run it but in the instructions it says the skimmer does best with 600gph input. I found this to be true; it does not do very well with ...Read More

Works great!

REVIEW
After the initial break-in period, the skimmer works great. The mag 5 works great on a 45g adequately stocked reef tank though AquaC says the ev-120 can be "supercharged" with the mag 7. No complaints thus far with mag 5 performance. The gate valve and air valve are very sensitive so you c...Read More

I finally bought this after careful consideration. I have noticed much more foam production after one week. I think overall it is worth the investment. I would recommend it highly

Not worth it

REVIEW
This skimmer is very difficult to get working in a consistent manner. I bought it to replace a older model Euro-Reef and after two months of endless frustration, I put the old skimmer back in my tank. The skimmate cup is extremely difficult to clean. The skimmer also is highly variable in bubble...Read More
