AquaC EV-240 Protein Skimmer Information


Product Manuals & Documentation

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.

Comments: This skimmer is amazing. I wish it wasn't so tall, but that's my only complaint. I read a lot of reviews about the break in period, but what worked for me wasn't in the manual. I started it up the the 1/8" connection plugged and the air vent valve closed. Over a period of 2 days I slowly opened the air valve. Now it's fully open and the plug removed. Skimming like crazy. I have it draining into a 5 gallon bucket that after 24 hours only has about 2" of skim mate inside.

Bubble Making Wonder

Comments: This Skimmer is a bubble making wonder. My old skimmer was just barely able to do the job, due to its design. This new AquaC EV-240 and its spray injection nozzle, coupled with the Mag 18 pump is truly amazing. I had dark green skimmate being collected in no time. This made me realize how well this type of system works. I like this type of design also, because it doesn't need a "sweet spot" level of water in your sump. It's a very good choice for my 225 gallon tank.

Comments: I have only had this skimmer installed for two days, but It produced gunk the first night! This is not your ordinary skimmer. I put the Mag 1800 on it and its very strong.High quality construction, It is easily adjusted, quiet, except for the projectile water shooting out the side. I had a problem with it splashing out of the sump and wetting my stand. I had to add a 90 degree fitting so it would flow down instead of out. You can also use a T fitting. (The 90 fitting will need a air hole to prevent syphoning the skimmer dry!) I highly recommend this skimmer to anyone .

Comments: It was hard to pull the trigger for this product because of the cost. I can tell you now 8 months later, it was worth the money. My tank had always struggled with algae green or red, I would get it under control then it would creep back. This skimmer has really made a major difference in my enjoyment level of the tank. Mark

Comments: I have been using this skimmer for 9 months. The skimmer produces a lot of watery skimate. My nitrates stay between .5 and 1 despite a slightly overstocked 125 mixed reef with a 55 refug. No problems with leaks but there is a small crack in the collection cup probably from cleaning every other day. It does get dirty quick especially in the neck below the collection cup.

Comments: I replaced my high end Tunze with this; and there is no comparison in the skimming volume. This skimmer with a Mag 18 is a beast! Tricky to adjust during the first week as it breaks in; so definitely keep the waste line inside the sump.

Experience Level: Expert


Comments: I've had it for 3 years now and only since I'm wanting to do more SPS did I find out that it's really not a good skimmer. I paid WAY TOO MUCH for it to do what it does. It's ok if it was cheaper and I just had a FOWLR or some other type of easy tank. The injector style is not very efficient. It goes nuts over the smallest things like using filter socks, just about anything. I have a MAG-18 on mine and the bubbles still won't reach the collection cup. Air Valve is open 100% too. Several people now tell me all of this. Should have done my research!!! The neck ends up with a ton of sludge which several affects the efficiency. Not a good product. Should have bit the bullet and did a Bubble King or something. People have these with SPS tanks and don't even need refugiums and things b/c it cleans the water so well.

Comments: Wow! Break in was 36-48 hours and watch out this skimmer produces bubbles like it had dishwasing liquid in the water. Installed out of sump with about 12" of level drain. Had alot of microbubbles, fixed this with a filter sock, just let it free flow into it. Water level was hard to see at first but adjustment is easy with gate valve/airvalve.This is my fourth protein skimmer, the previous three where junk as they just sucked air thru a little 1/4" air line and hardly produced any bubbles or skimate.
