Need to know if this item will hold 3 cups of activated carbon. Also double checking to make sure this can be used as a Carbon reactor. Also I plan on using a existing MJ1200 with this unit.
Question by: Scott on Apr 24, 2014 12:11:00 PM
Hi Scott,
This is an air filter, it would not work as a carbon reactor as it has the incorrect size and type of fittings. For a carbon reactor you would want this model:

I have a Biocube 29 with the coralife protein skimmer. I wish to install this between the air pump and the skimmer. Are the air hoses on your air filter the same size as the air hose that is used in the protein skimmer. If not do you sell an adapter?
Question by: Jon on Feb 24, 2016 7:27:00 AM
Great question!
Unfortunately we cannot verify if your skimmer has the same airline size however our air filter will have standard 1/4" airline tubing. I have attached a link to several of our Kynar adapters which have varying sizes of barbed fittings.

I need to find a different elbow with a 3/8" barb fitting to fit my skimmer airline tubing. What size is the female threaded input that the 90 degree airline elbows are connected to?
Question by: Leon Thai on May 16, 2016 12:02:00 PM
Great question! The kynar elbows we use on the universal air filter are 1/4" thread by 3/6" elbow. If you are looking for an alternative barbed fitting, it will need to have a 1/4" npt thread to fit on the canister. If we can be of further assistance, please let us know. Have a great day and happy reefing!

If i have my protein skimmer vented outside do i still need to use universal air filter. thank you
Question by: james on Nov 4, 2013 1:19:00 AM
Hi James,
Both of those would be optional but adding a universal air filter with co2 absorbing media would help to increase the pH. Because your already using a source of lower co2 air to begin with the effect won't be as noticeable but the media should last longer.

  • More positives then you realize! By Matthew on 5/1/2016

    Wow this product combined with the co2 absorbent media is actually one of the best investments to date I have made for my reef tank. Originally I ordered this because my ph was hanging alittle low for what my expectations are at 7.8 without running a calcium reactor so I figured I'd give this a try. I hooked this up to my Aquamaxx hob-1 on a 40g breeder mixed reef and first of all it is the number 1 silencer on the market and they don't even advertise it like that and it has been about a month now and my ph has been dead stable at 8.3 the only other additive I use besides roids and fish food is bright well Kalk+2 havent made any other changes and my corals have just been looking so much healthier my Monti caps blew up awesome polyp extension pretty much all day everyday from acan lords to Duncan's to candy canes not to mention my torch is pretty my trying to sting my neighbors across the street and I really can attribute this success to this product with the co2 absorbent media it already paid for itself just by silencing the skimmer. The media had to be changed about every ten days for me at first but I actually ran air tube outside before I ordered this and decided to hook that up so pulling air from outside through this reactor then to the tank it has been ten days now and the media is only a third depleted so it is looking like once a month which is perfect I'm assuming that is because there is less co2 to scrub from outside then inside it is kinda like di resin and have cleaner tap water it lasts longer. I am totally happy I grabbed this thing if anyone has a Aquamaxx hob1 skimmers the works great on a breeder but it actually pulls air surges this thing has calmed it down and it has been functioning more efficient for me as well. Super low maintenance it doesn't get dirty maybe dust the thing twice a year and switch the media when it turns purple or just use it as a silencer for the skimmer lol. I mean really I thought I was wasting my money when I pulled the trigger on buying this and I was far from wrong and will be using this on all my tanks from this point forward I mean this thing has giving me like miracle mud urban legend results and I couldn't be happier with this purchase. Happy Reefing!!
  • Works exactly as advertised! By Lloyd on 3/23/2016

    I use it for a CO2 scrubber with soda lime to keep my pH up when my house has to be closed up for any season or any reason. The canister works great, keeps my pH from 8.2 at night to 8.3-8.4 during the day. Like others have said, the stock tubing and elbows need to be changed. I used a silicone rubber tubing from BRS that you usually find as extra with protein skimmers, and took off the elbows that came with it, installed 3/8" ID fittings and it draws plenty of air with no decrease from that of the open atmosphere, except the air going into my skimmer now has zero CO2. It's perfect for what it was designed for; I used one previous to this as an air dryer for an ozone unit, and it was perfect for that as I used a Luft pump to get air through it. It's well worth the money, whether as ozone air dryer or CO2 air scrubber.
  • Well made and works well By Tad on 11/24/2015

    This is a very well made filter and it does what it is designed to do. Like many others, I use it as a CO2 scrubber. Its easy to set up and when using it with color changing soda lime, its easy to see when to change the media.
  • Great! By Artem on 11/3/2015

    It works!
  • It's great By Steven on 9/17/2015

    It does just what its supposed to do, its a cheap efficient media reactor.
  • Great CO2 Scrubber By Adam on 9/14/2015

    There are 5 of us in this house and my 225 gal total volume system is downstairs. When the windows are closed in summer and winter, my Ph dips very low. This air filter in conjunction with soda lime attached to the intake of my skimmer has raised my Ph significantly. I did have to trek to the hardware to replace the hose barbs as they are too small for my BK Mini 200 skimmer but that was $5 and very simple. Very pleased.
  • great By ol crusty on 7/14/2015

    Great easy to use combined with co2 media it is an easy and effective way to get your ph upth
  • Air filter By Seth on 12/2/2014

    I am using this as an air filter filled up with bituminous carbon for my skimmer line that is run outside. The quality of the reactor is very good. I have no way of measuring whether the air filter is working but my corals are happy and don't seem to get irritated when I'm on the patio grilling or BBQing and smoke is going towards the filter. Before the filter they would get irritated.
  • Set up as a CO2 Scrubber By Alan on 10/16/2014

    Great product and an easy set up. I used this for a CO2 Scrubber but the tubing and elbows should be changed. I measured the air flow from my skimmer after I got it hooked up and it cut the flow by almost half. After I disconnect the elbow on the inlet side and add a larger elbow and larger tubbing, 3/8"ID, My air flow is back to normal. My PH is sitting at 8.3 from 7.9. Very Happy but they should give you an option for large fittings and tubbing.
  • Would recommend this product By Brian on 3/5/2014

    Great product, helped raise my ph from 7.9 to 8.2-8.3. The hose that I hooked to my skimmer is a little loud. Both opening on my skimmer are connected to the air filter, so it has a lot of suction.
  • Fantastic By bv on 2/22/2014

    I used this product and in one day it took my Ph from 7.99 to 8.29, one day!!!
  • Great Air Filter By Anne on 12/30/2013

    I bought this in conjunction with BRS's CO2 absorbent media due to low ph issues. Since running this filter with the CO2 absorbent my ph has come up by about 0.2 and has been stable for awhile now.

    The filter itself is of quality design and made from durable materials. The mounting bracket and media canister system are very nice features that make this product convenient to use and basically eliminates the hassle involved in changing the air filter media.
