Product description

Seaclone's exclusive turbo-venturi injector system mixes filtered water and air in the pump impeller chamber, creating a froth of micro-bubbles for maximum skimming efficiency and improved gas exchange. Air and water swirl together in the vortex reaction chamber, creating a powerful tornado effect that rapidly draws dissolved wastes from aquarium water. The spiraling air/water mixture propels protein-laden bubbles upward, where they burst to form a frothy solution.

• PROTEIN SKIMMER Mini vortex skims and removes dissolved wastes from marine aquariums
• POWERFUL & EFFICIENT Turbo-Venturi Injector System with Maxi-Jet 1200 pump form protein-laden bubbles
• VERSATILE INSTALLATION External hang-on or in-sump installation
• CAPACITY Works with any marine aquarium up to 100 gallons

User questions & answers

Question:	Does this skimmer come with a pump
Answer:	Yes. comes with a power head and is ready to go out of the box
Question:	is this item loud its going in a bed room
Answer:	yes it will be loud in bed room you should leave it living room
Question:	Does this run on 220v
Answer:	No
Question:	this hangs on the back of a tank
Answer:	Yes. You need about four inches of clearance (the width/depth of the skimmer) behind the tank. Mine is the 150, but I think the only difference between the 100 and the 150 is the length of the tube, not the width/depth of the skimmer. I had to get a replacement because I fried the pump impeller, but both systems have worked well and have not leaked.

User questions & answers

Question:	Will it fit in the back chamber of a biocube 32 gallon
Answer:	I can't tell you that for sure but this is a bit much for that tank. They make a smaller version of this. I have this on a 75.
Question:	Anyone figure out the bubbles issues? I can't get them to stop
Answer:	As Tom Campbell said, get a 1/4 inch Barb Valve from Home Depot used for drip irrigation and zip tie it to an inch of the yellow hose you have to cut off. You can then regulate the airflow just like every other protein skimmer ever made. Horrible inexcusable design flaw. Valve costs less than 2 bucks. Also look into the output bubble filter thing they sell as an option. The first time I turned this thing on was a catastrophe.
Question:	How do u connect the collection drain pipe intoe xternal drain
Answer:	The lid for the right side of the skimmer has a air hose and silencer for the Venturi and on the lid it has a corner missing. That corner would be turned where the overflow pipe can slide in to the chamber. And it’s not a cup drain, it’s purely an overflow so if the cup isn’t changed the skimmate won’t run in the floor, it will overflow back in to the skimmer.
Question:	Will this unit fit if you have a canopy top or does it sit back far enough to clear the canopy
Answer:	What do you mean by canopy top? If you mean one with hinges that goes opens toward the back of the tank, the skimmer is at 90 degrees so it would be close. You also have to account for the plumbing going into the tank. I have a biocube 32 and it does not work with the lid. If you have more questions or this doesn’t help PM me on IG @ bhmcubereefer

User questions & answers

Question:	Hi, My 60gal is in the bedroom, is this skimmer silent
Answer:	The skimmer has a fizzing noise (but mind you have been running it only for 5-6 weeks, some people say it goes quieter afterwards). Not an expert on skimmers as this is my first so dont know really how it compares to other skimmers. There is a slight gurgling sound (from mixing water and air) but the fizzing is what i would call noise. Tank is in my living room so not a problem for me really. Hope this helps
Question:	will this work on a 24gal jbj nanocube
Answer:	This works very well on a 40 gallon so no reason I can see it would not work on a 24. Its a very good HOB skimmer.
Question:	Will this work on a 125 gal tank
Answer:	It's only rated for tanks up to 100 gal. You will need a larger skimmer.
Question:	Will this work on 75gal tank
Answer:	I have a 65g tank and it works perfectly fine. I think this is rated for up to 90g.

Question:	To anyone that owns this unit....how loud is it compared to an AquaC Remora? Mine is incredibly loud and I do not like the pump in the tank. Thanks
Answer:	I purchased the BH-2000 to replace an Aqua C Remora. The noise difference isn't noticeable and I like not having the collection/outflow box "hanging" in the tank. I recommend the BH-2000.

User questions & answers

Question:	Did you get the model just like the picture (Red and Yellow Box) or the newest model (blue and purple box
Answer:	I received the blue and purple box.
Question:	will this be ok on a 55gal tank
Answer:	Yes, I am using that on my 55 gal tank, sometimes I even turn it off during the day time.
Question:	I bought this skimmer - 65 gallon version about 6 months ago and now it is not working. Does this have any sort of warranty
Answer:	I have all of the versions of the coralife super skimmers 65g, 125g, and 220g. I have found first off, they are good skimmers, they do need regular cleaning and maintenance, especially with salt buildup in the air line leading into the pump, salt builds up over time and slowly chokes off the air supply to the needle wheel impeller. I have found the the 65g does require cleaning a little more often than the other models. I hope this helps, clean out the pump, remove and scrub off the impeller being careful not to bend the needle wheel.
Question:	hello , what is voltage 220 v or 110 v
Answer:	It was purchased as a gift for use in USA so it is 120V check with manufacture for multi voltage use

Question:	Will this fit a nuvo 40 compartment in the back? If so which compartment
Answer:	I have it in compartment two in my nuvo 14. Might be similar?
Question:	Does it come with the rock for the bubbles
Answer:	The skimmer comes with the venturi pump to make the bubbles. It does not come with rock.
Question:	Does anyone know how high I should adjust the bubbles on this? Either overflow or no skim
Answer:	Take the top part out while it's running. There should be foam. Insert the top part with the lid and stop it right as you see the bottom of the cone start to fill with foam. It will end up funneling through the top and in to the container. It took a while for me to get mine just right. Hope this helps.
Question:	How much space is needed above the top of the tank? My tank is under a cabinet
Answer:	Depending on the size of the tank, no additional space is required. The skimmer can be used inside the tank, or adjusted to higher levels with the included hanging hook. The cup for debris can also have its height adjusted. If you needed it to, the total height can be no more than the stated dimensions.
