As we don't carry the JBJ rimless tanks, I'm afraid we can't make this test ourselves. However, in talking to our customers, they have found the Comline 9004 to fit in the back of the 45 rimless tanks.
Hope this helps!
The 9004 DC Skimmer now includes a DC powered pump and controller for ultimate control and tuning ability.
The Tunze Comline DOC skimmer utilizes Tunze's "Flash Skimming" principle. The skimmer is quiet and generates a very large volume of small bubbles for efficient skimmer operation. It operates stand-alone without needing any additional equipment (feed pumps, etc) and mounts to the tank via a convenient magnet holder strong enough for glass up to 1/2" thick.
The TUNZE® Foamer generates large volumes of fine air bubbles with a diameter between .0039 to .011 in. (0.1 to 0.3 mm) On the surface of the air bubbles, pollutants such as protein, cellulose, dead cells, etc. are adsorbed immediately. The water/air mixture expands and stabilizes in the skimmer cup reactor, the water returns to the aquarium, and the protein-loaded air bubbles spill over into the skimmer cup. The patented anti-overfoaming system intermediate chamber prevents the skimmer from over foaming and controls the skimmer performance, depending on the water level and organic load. This “flash skimming” principle, compared to large skimmers with long contact time, is obtained because the substances adsorbed by the air bubbles are not released again, thus they don‘t return to the aquarium water.
Awesome nano skimmer By Erik on 9/5/2017Erik would recommend this product to a friendOnce installed the skimmer instantly started producing skimate after a week worked even better. Very impressed and worth every penny to improve water quality.
Great for its price! By Alex on 5/21/2017Alex would recommend this product to a friendThis skimmer is great.It started producing skimmate in less than 30 minutes.This skimmer is awesome with the DC model. You might be thinking it so expensive, But this has cut my algae in half. It's very cool with the cup collection feature.The only downside is that tiny micro bubbles slip through the collection cup and the main unit but its very minimal. Hope this helps.
Awesome skimmer By Kyle on 1/6/2017Kyle would recommend this product to a friendSo I have this skimmer in the Nuvo 40 and I absolutely love it I have it in the first chamber and it does restrict some flow but it worth it. It's been in tank for about 24 hours and already has some dark nasty skim mate in the cup. It's super quiet can't tell it's even on I hear my return pump over this skimmer. I picked up the one that you can control and I am glad I spent the extra money for it well worth it. Don't worry about this buy you will love it. Thanks BRS for carrying another awesome product .
Awesome By Lee on 12/19/2016Lee would recommend this product to a friendFantastic skimmer! I purchased this skimmer slightly oversized for my tank (29 gallon) primarily due to the adjustability for bioload and surface skimming capability as I don't have a sump. Could not be happier. Pulls out some nasty gunk. Don't worry if it is a little noisy initially, once it breaks in the skimmer is practically silent. Thanks BRS for carrying Tunze skimmers...
Great product with a compact design By Kenny on 10/23/2016Kenny would recommend this product to a friendPurchased this for my JBJ RL30 and live the sludge it's pulling from my tank. Very impressed with the dark skimmate from a nano sized skimmer. The DC motor allows for true adjustment to fit your bio load needs. Another great product from a trusted brand.
GREAT Bought another By darryl hey on 8/1/2016darryl hey wouldn't recommend this product to a friendMy second one, another great product from Tunze.
works great and is easier to control the air for a nice DRY skim.
Plus it can be hooked up with safety box to make it battery operated in a power outage.
