A few kinks By Keith on 11/8/2018Keith would recommend this product to a friendLike some of the reviews above, I had to take off the 90 degree elbow and it works fine. However, the problem that causes, is the square filter pad that is provided does not stay at the bottom of the skimmer. It occasionally floats over the outlet which is normally OK, but once it gets filled with gunk, it restricts the outlet flow and the skimmer overflows onto the floor. It works great at pulling stuff out of my 150 gallon fully stocked mixed reef, but it has some design flaws that you need to work around.
Great skimmer, terrible description By K on 11/6/2018K would recommend this product to a friendLove the skimmer, but the dimensions on this description are WRONG!! It made a huge headache for me trying to get it on my tank in the space we had available. Correct dimensions are 24.4” x 3.9” x 9.8”
Works Well! By JJ on 6/5/2017JJ would recommend this product to a friendI picked this up for my 125G 6Ft Display tank. It does a fantastic job! At first it created millions of microbubbles, but after a few months they went away nearly completely as the film started to build inside of the system. I clean out the skimmer bucket daily keeping it completely clean and do not touch the rest of the system. I put the carbon circles over top of the outtake holes where the bubbles were created.
This thing picks up all kinds of yucky stuff daily, and my tank remains pretty clean! I am very satisfied, well worth it, especially if you don't have the room for a sump like me and relay on a can filter!
Can be finicky, but WORKS By Amy on 5/3/2017Amy would recommend this product to a friendMan, this thing pulls gunk from our 75g. Started producing the most disgusting smelling skimmate I have ever smelled (and I've worked with fish for years), right from day one. After a few weeks of 'breaking in', it worked even better. I have to clean the cup daily or thick sludge builds up in, on, below and around the cup. We have a lightly stocked, lightly fed barebottom tank with 2 filter socks changed daily. Long story short, this skimmer fits in tight spaces (we have it on the side of the sump) and yanks a crapton of goo out of the water.
Amazing Skimmer!! By George R. on 4/11/2017George R. would recommend this product to a friendFirst thing i must say is that BRS is simply amazing! I purchased this unit and it was faulty....one of the fasteners were damaged, it did not move to tighten onto the pump but BRS made the replacement process a breeze! i will never hesitate to purchase from BRS for all of my future needs!
now lets go on to the product.....setup required youtube as the instructions were non existent except for a diagram. Micro bubbles were a huge annoyance for the first 2 days but then i started playing with the foam rings and blocked about 80 percent of bubbles *i had no idea they were to go over the outtake holes* the remaining 20 percent of bubbles were due to the powerheads ....try moving the powerheads away from the skimmer outtake and problem solved! i have absolutely no microbubbles now. the skimmer collects so much crap it is unbelievable. you must get this NOW! i have a 75 gallon with 9 fish and about 11 frags and the amount of skimmate collected is crazy! I must warn you....if you have small fish or shrimp and you have not seen them in days...check the skimmer! i have no idea how they get in there with the cap covering the intake but they do and having to rescue them sucks but that does not take away from the greatness from this skimmer!.
It works! By Chivo on 12/21/2016Chivo would recommend this product to a friendI've had this skimmer for a few months now. I was surprised by the extremely short break-in period and the amount of waste it started collecting right away. Going HOB was the perfect solution for my Uniquarium, which has a ridiculously small space on the back for a skimmer. I did have to search in Youtube to figure out how to put it together since it really has no instructions. But it works, does it's job and I'm happy.
Working thanks to ONALASKABILL! Still too loud for living area... By Rick on 11/30/2016Rick would recommend this product to a friendI was getting extremely irritated with this skimmer until I read the review from ONALASKABILL. I have the skimmer on a timer to avoid the few hours we spend in the same room with the tank watching TV, as it is pretty loud (100% pump noise, no gurgling, etc.). Unfortunately, it would overflow each time it turned on, unless I was there to adjust the collection cup way up (and then back down, or it wouldn't collect anything...). I took off the elbow in the return, and it is like night and day. It pulls way more out, and never even comes close to overflowing.
A++ By mike on 10/30/2016mike would recommend this product to a friendWorks like a champ!
Works great after some tweaking By OnalaskaBill on 4/30/2016OnalaskaBill would recommend this product to a friendI guess I should start off by saying the skimmer is working fine now. But I did have some issues until I figured it out.
As noted by others, the "instruction manual" is a bad joke. I'll just leave it at that.
After I got it put together and hung on the aquarium, upon powering up, it immediately started pumping clear foam into the collection cup that filled the cup in a few seconds, even with the cup set very high. I put the air valve thingie back on and cut off some of the air to get it to stop flowing into the cup. At this point the skimmer was blasting bubbles into the outflow chamber and into the aquarium. Also, the water was gurgling up a storm on the outlet pipe. I decided to let it settle for a few days to "break in", but I was close to packing this up for a return trip.
I was curious what would happen in the case of a short term power failure so I did some testing. When cutting off the power for a few seconds and then back on, 50% of the time the outflow chamber would overflow water onto the floor. Well, that won't work. In addition, the microbubbles were crawling up between the body and the cup and dripping onto the floor. I had to tie a rag around the skimmer to soak up the water as it bubbled out. If I lowered the cup so the bubbles would not creep up, the cup would fill with white foam in a few seconds. I would have to live with the aquarium any time the skimmer was running?
I tried putting some bubble foam in the outlet chamber but that did nothing to help. While removing that, I knocked off the elbow piece on the outlet pipe, and it was like a miracle happened. The skimmer sopped putting bubbles into the tank, the cup stopped overflowing, no gurgling, and the bubbles stopped creeping up the side of the cup. Apparently the water LEVEL is the key to the whole thing.
I can only assume now that this skimmer was designed for a rimless aquarium with the water level an inch or two below the top. I have a standard rimmed aquarium and like to keep my water level near the top so one cannot see a space between the water level and the plastic rim.
This was my downfall. Rather than keep my aquarium level down 2 inches, I just left the elbow off of the outlet pipe.
The skimmer now works like a champ. I get a quarter inch of "dark tea" per day. I have a very light load with only 4 small fish in a 75 gallon setup that is only 4 weeks old. I have no doubt that this skimmer will do well even after I add more fish in the coming weeks.
AMAZING Skimmer By James D. on 4/13/2016James D. would recommend this product to a friendThis is probably one of, if not the best skimmers that I have owned in the past seven years. I need to clean this DAILY. It pulls out gallons of extremely dark, nastly, and smelly skimmate. Though it it labeled for approx 125 gallon tanks I would not put it on anything bigger than 60 gallons. Anyways, amazing skimmer and I would reccomended it to everyone.
Have had mine for three yrs now .Looks new yet Love it Works excellent...buy it turn it on wala. I empty mine once a week clean whole thing twise yr. By Rose on 4/12/2016Rose would recommend this product to a friendJust get it you wont regret it !
Leaky skimmer By merlinpi on 11/6/2015merlinpi wouldn't recommend this product to a friendgot the skimmer, assembled it according to figure and online video that coralvue has, leaked from the elbow unit connecting the pump, customer support was fast and responsive. But still leaky after 3 elbow, returning the unit. Cannot afford having a leaky HOB skimmer where the leak is on the OUTSIDE if the aquarium...
Hi I'm looking at hanging this off my sump how many inches is needed from top of tank to bottom of skimmer?
