SWC 1A Cone skimmer review

First off thank you MOJO for your many skimmer reviews. They have helped me and other reefers make some educated decisions about skimmers. It also opened my eyes to brands I would have overlooked, such as the Vertex brand. Which turned out to be one good bargain skimmer. All though I don't have the luxury to test as many skimmers as MOJO, I have had in the past a Top Fathom, ASM G3, Euroreef CS 6-3,CS 8-2,CS-8-3,CS 12-1, Reefmania 12" x 36" tall three sedra, Vertex IN-250, H&S 3 x Aquabee, 2 do it yourself skimmers. I've also played with many pump variations on those same bodies with the Sedras and Sicce pinwheel and mesh versions, two different Askoll 1500 pumps and needlewheels. All this did for me was want a skimmer right out of the box that was engineered good with its pump to work well with the body. I also wanted to do no modding.

I was looking for a skimmer that can handle a large tank. I have a 180 plus 75 gallon sump so 255 total water volume. Heavily stocked with an Achilles tang, Tomimi Tang, Foxface, Clown, 2 x fire fish, Mystery Wrasse, Copperband, Anthia, Flame Angel, Pipe fish and a Manderin fish. Lots of LPS and softies in zoas, rics, favia and acans, chalices and leathers. There is an island in the middle with three Rose Anemones, which get fed all the time. I'm hoping for them to add clones and to have a giant Rose Anemone island. Need less to say they add lots to the bio load.

My short list on my search was the Hurricone CAT-2, Vertex Alpha Cone and the SWC 1A Cone. After lots of research I've decided on the SWC 1A Cone for now. Hopefully it was good decision, only time will tell. I'll share with you my experience, and here is how it arrived.

It came with easy to read directions on how to put it together. First impression, is the acrylic is very thick. A nice bonus. The seam less body looks very good.

The bubble plate is removeable and is really two parts, so it can be taken out of the skimmer for cleaning.

The cup is large with a simple drain plug connection. Similar to the one on the Vertex skimmers. I've used them before and they work well. Simply remove the plug and place the tubing onto it, if you want to use it. The lid is carved with SWC's logo, it looks very clean.

Following the directions, it was easy to put together. The cup slips in and fits super snug. Easy in, easy out. No twisting.

Here is the Askoll 1500 by SWC. First thing I noticed is it's been injected molded. Slightly different than BK's Red Dragon an ATB's Airstar, which I believe are milled. A little getting used to, since it's the first of its type. After talking in depth with some employees at SWC, they are saying that this version has the ability to run 90 SCFH or 2500 LPH! They tuned it down to 75 SCFH or 2100-2200 LPH to match the body. That was all the conversation that I needed to make up my mind that I needed to try this skimmer. I am super excited to see what this pump can do.

A bonus that comes with this skimmer is the ability to run it single pass or in recirculation. I am choosing to run mine in sump. But it is nice to have this option. Here is the additional tubing that was included to make it a recirculating skimmer. I may use it this way later, just to see how it works, but for now it will be in sump. The tubing size was increased for 2009, which is better suited for the new pump. It's a very flexible option, other brands aren't offering.

Another nice thing that I noticed was the Askoll pump connects to the SWC cone by a union. A small improvement from the silicone tubing used before.

Straight out of the box, wiped her down with a wet towl. My skimmer sits at about 8 1/2" of water. The SWC guys recomend 8" for optimal performance.

First thing I notice is how quite this pump. Super quite. The silicone tubing for the venuri is extremely thick, much thicker than any other brand skimmer that I've used. The skimmer pump is so quite that I am not sure the silencer is needed. Here is a picture of the silencer. I like that the tubing is easily removed. I often clean the tubing with RO water, to melt away salt build up to keep the pump running at its best. Notice the two tubes to supply all the air for this monster of a pump.

Pump fired right up and as the body filled with bubbles the transition from the body to the neck was turbulent free. The whole skimmer filled with little tiny bubbles. Here is a close up of how fine the bubbles are. The transition from the body and the neck is very very smooth. Before starting it I ran my hand through the body and neck looking to see how well the transition felt. It was one smooth continuous wall, nothing to disrupt the rising bubbles. The bubbles should even get smaller and finer when the skimmer breaks in. There are very tight seams where the cup and body connect. I really like this neck connecting.

Nice! I have the previous version. the new volute and lid connector look cool!, my Swc a1 works great. It just skims away and keeps skimming I've got nice dark skimmate and the water is sooo clear. I would love to see one of these newer versions go up against some of the others. Is the neck 5.5"?. any pics of the needlewheel? tia.
 
Bogg the main difference that I can see from last years to this years is the pump, and the neck diameter increased to close to 5.5 inches from 5 inches. The skimmer is also taller by .5 inch to 1 inch. I can't measure it right now, cause its in the sump. But I believe the neck got taller by the extra inch. Which puts this skimmer at 24.5 or 25" tall. Just a tad too tall to go into 24" stands.

I don't have a picture of the needle wheel. Right now I plan to pull the skimmer out in a week or two to glue the union and pump together. I was waiting to see how it works first, before glueing anything together. If I can remember, I'll try to take a picture of the needle wheel when I pull it out. I think there is a picture floating around reef central of the needle wheel posted by Marine Solutions.

I would love to know how it runs as a recirculation type skimmer. I am still liking to keep my skimmer out of the sump. You could keep it out of the sump if you hooked it up like that, right?
 
The tubing is for a recirculating IN SUMP set up. It allows for you to skim recirculating. Not to be confused with external recirculating.

At this time the Askoll runs hot externally. BK and the Hurricone have worked on an anti lime loop that cools the external pump. I am not aware of SWC offering this option yet. I believe they are working on it though. On one of the pictures you can see a nipple extending from the side of pump volute. I asked about this and was told it was there in case I wanted to drill my own anti-lime loop similar to Hurricones and BK's. So since they planned for it to be there, it must mean they are working on an external pump. This is my opinion though, and you should call MSX or SWC to find out. Running the recirculation in sump allows the pump to run cooler and there is no need for the anti lime loop.

GC I am waiting for the meter still. Jayson at SWC told me he tested my pump prior to shipping and it was getting 75 SCFH on his skimmer body. I'll post my results as soon as it arrives.
 
I have last years model as well. I have really learned not to jump on the first generation of anything. I had volute problems, and this new one looks much better. Now that I have things corrected, I have been very happy with this skimmer. I run a 300+ gallon system. However, I'm not sure the wider neck would be a bonus for me. This skimmer can already easily accomodate my system, and I'd be afraid that an even bigger neck would result in less skimming. I can say other than the old volute the skimmer craftmanship is excellent. Very solid. Cup comes off easy but also fits snugly. The collection cup is huge, and I empty it about every ten days. Given the quality, askoll and recirc options, I believe this is the best cone available right now.

Oh dang it. LOL.
 
Tufcody I'd heard about the variable results from other people on the grey volute made by CNC. I even had one, and got lucky cause it worked extremly well. This was a concern of mine and kept me on the sidelines for a while, when I was doing my research. I asked about this specifically to the guys at MSX, SWC and both assured me that the new white volute is better and much more reliable. They both said it is extremly reliable, because they are all the same, because they are injected molded. They also said that the new white volute pulls MORE air, hence the bigger neck. I hear your concern on wide necks, and wondered if it was too big of a skimmer for my tank. I agree that if all works well, it should handle larger tanks than the 5" neck. I will let you know my results. Rather than judge one way or the other, I'll just call it play for play as the skimmer skims. Right now there is a nice thick foam head already. Only a couple of hours into it.
 
I would still like to know how it runs recirculating.

I am new to these types of skimmers, so could you explain something to me. If you have it in the sump, then the pump sucks from there and pumps water and air into the body, right. Then the water exits the body through the wedge pipe,right. So then what is the other fitting on the body for in the picture? Is it just to hook up the pipe to make it a recirculating skimmer? And if you don't use that feature does it just have a cap or plug or something?

Sorry for the dumb question, but I have never ran a skimmer like that, and I really like that one. And might get one or something similar in the future.
 
Here is picture of the skimmer taken off of a retail site with the recirculating plumbing hooked up. You feed water into it from your drain or from a pump. There are many who like this feature. The idea is that there is more contact time, so everything that can be broken down and skimmed, eventually does. I prefer in sump skimming. I just used the cap that comes with the skimmer to close the union that isn't being used.

Awesome, been waiting for a review on one of these. Lets see a foam head as soon as its ready. Also, just to be clear does the new model pump also put off heat, and if so enough to translate into a display large like yours. At 65 watts or whatever that pump runs at, I figure it couldn't generate heat like a larger (non-redragon) skimmer pump.
 
Very nice! Look forward to more of the review.

You can see what they changed from last years model. They cut the cone a little shorter to increase the neck diameter and made it up with a taller cup neck. The pump looks like a nice improvement. Is the neck the same 5.5" ID as an MSX250?
 
Well I woke up to a nice suprise. Foam all over the neck wall. Dark skim mate in the cup. The next three pictures are after running about 20 hours. I set the skimmer water line low at first. Two inches below the bottom of the cup. It rose for a few hours, settling at about two inches below the top of the neck. From what I know about skimmers the skimmer should still be breaking in, but from the looks of it, I'd say it's already broken in.

First reaction to the cup is noticing how dark the skim mate is. Of all the skimmers I've had, this is close to the darkest skim mate I've ever had. Second is how much skim mate I have for such a short period of time. It used to take a couple of days for my older skimmer to have skim mate cake onto the sides of the neck, like that. A small feature that I like, is the beveled edge on the top of the neck(see photo of top down shot). It appears to help the skim mate over the neck. You can actually see particles of skim mate every where in the foam.

SJM I've been told it is 5.5" but will measure when I take the cup off.

ARI the pump works well in sump and was designed as an in sump pump. I don't believe it puts out any more heat than my Sedra 5000's ever did. I wouldn't know how to measure it though, other than if my temp started to rise. My water temp is the same as it was. Red Dragons and Airstars have been running for a while, with no one reporting extra heat, and they are the same pump engine. So I wouldn't worry about it while it is in sump.
