I purchased the CS1 Cone Skimmer about a year ago. I can just say WOW. I replaced a Euro-Reef RS80. I was surprised how easy it was to build and the excellent and rapid support I received from Justin Casp. After running the skimmer for 10 months, it runs as good today as the day I purchased installed the skimmer. The waste is much darker and consistent that the Euro-Reef. It ran for a few weeks and filled up often as the Euro-Reef really did not work in the same league. I also purchased the swabbie and skimmate locker. What a joy to run and clean in comparison.

I purchased the CS1 and am impressed by it's performance. I decided to use a dc pump and the guys at avast were a great help and machined a venturi to match the pump. The skimmer has been working great and I couldn't be happier with the customer support.

Amazing Skimmer for the money, comparable products are 2x the price and don't look nearly as nice. Highly recommend this for anyone looking for a powerful skimmer without breaking the bank.

I have been using the CS1 for over 2 years. The build was easy even though I am not much of a DIY guy. I had a fun afternoon putting it together. This skimmer is the BEST BANG FOR THE BUCK out there. It skimms wet, it skimms dry it skimms however I set it. I will never use a non-recirculating skimmer ever again! No more worrying about water level in my sump! The PSK 1000 RECIR PUMP is a workhorse and is silent. I also ordered the Swabbie kit FOR SWABBING THE POOP NECK! THIS SKIMMER IS PURE YAR!

Ordered the CS1 kit with pump about a month ago. It sat in the box until I had some free time to do the build. It's a little intimidating at first but once you get going it's a real breeze to build. If I did it again (CS3 maybe) I'm sure my seals would be much neater. Regardless it's built. It's currently running in my sink with a vinegar and water solution and will be inserted into my sump later today. VERY HAPPY with this purchase.. For a 1/3rd of the price I now have a recirc skimmer!

One of my favorite skimmers! Works like a charm, was a lot of fun to put together and looks great with the dark body. It doesnt take up a lot of space in the sump. Love it!

Well what can I say I did not get the chance to build this myself as I bought stuff from a reefer going out of the Hobby. This skimmer runs like a champ and put my reef octo to shame. it slims nice and dark and the amount is constant. It was used for 6 months before I have received it. After a bath it is back in use and skimming like no tomorrow. With 110g total it is doing a nice job with filling 3/4 of a cup in a week and a half. it is a nice small foot print and allows for me to feed my fish when I shut the pump off no annoying over flow form the water rising. If you want quality here it is this is the skimmer you want.

Bought this skimmer a couple of weeks ago. Easy to follow instructions. Great customer support. Skimmer works fantastic, is quiet and efficient. Well designed and will be easy to disassemble and clean when the time comes.

Let me just say-WOW. Great quality materials, they felt very robust and durable. I got this kit as a gift and I can gladly say, It was one of the best gifts/ projects i have ever received. Assembly was a breeze and it was a great weekend project and helped me understand how a skimmer actually works. It pulls out some pretty nasty stuff that smells rank.
