In this video, Paul from Red Sea walks us through all of the features of the Red Sea RKS, including Performance, Quiet Operation, Quick Maintenance and Cleaning, and Multi-Position Assembly. Thanks Paul!

The RSK Reefer Skimmer Series is the most high-tech skimmer system currently available, including multiple features that we believe should simply be included standard with all protein skimmers because of their effectiveness.

We outlined the main features of this skimmer in the "Specs" tab, but the uniqueness of the RSK Skimmer can be summarized in three words...Ease. Of. Use.

For example, the Foam View Window. Why this hasn't been implemented until now is beyond us. We've been trying to look through black skimmate to dial in skim levels for years wondering why there wasn't a small porthole that we could see through to what the actual level of the foam was, instead of trying to contort our head around at odd angles to try and find a clear spot to look through. And if we don't have visual marking indicators on our Skim Level Dial or forgot to put them in ourselves, we are forced to go through this rather annoying process every time we do maintenance cleanings (making us less likely to do them). Thank you Red Sea for finally delivering on this simple yet invaluable feature that makes the life of a reefer that much easier.

A piece of the skimmer that helps tremendously with simple maintenance is the INCLUDED Manual Neck Cleaner. Yes, we emphasized "Included", because there are a few skimmers out there that do offer a neck cleaning solution, but they are separate purchases, adding a price addition to an already fairly pricey piece of reef equipment. It's just a nice touch that it comes standard. Keeping the neck of our skimmer clean also rapidly increases performance (by as much as 40%) because the bubbles are allowed to flow and move properly, where if they get met with gunk along the way, they can slow down and break before reaching the collection cup, effectively wasting foam and not getting our full money's worth out of our skimmer.

We could go on about the pros of these skimmers for hours, and honestly, there's not much to say about improvements. One thing we'd really love to see however is a slightly smaller / slimmer version of these skimmers. While it is a high-performance skimmer, compared to other standard line skimmers the cone-shaped body is a bit wide at the bottom. The body size is still more than manageable if the skimmer has its own dedicated chamber, but for those of us who want to run additional equipment (like media or bio reactors) or just don't like the look of a cluttered filtration system (for aesthetic, flow, and cleanliness purposes), then a "Slim" option that is 1 - 1.5" smaller in diameter would be ideal.

All in all though, the RSK Series is one of the most solid skimmer options out there, and once we experience the Ease of Use of some of the RSK's features, it admittedly becomes very tough to live without them.

Have any further questions that aren't answered here? We'd love to hear from you, and learn how we can help you be as successful as possible in this wonderful hobby.

So...late one night I was shopping online for a new seahorse tank. I ended up on the Two Tides website & in the bottom corner it said to click for a live chat. Since it was after midnight & they’re in the same time zone, I thought no way. But I clicked anyway & sure enough I was chatting with a live person! We chatted for over an hour until he asked for my email address telling me I’d be contacted the next day. That’s when I met Tyler. He helped me with my purchase. He went above & beyond to get me the tank I wanted, even spending a day on a video chat with Pro Clear Aquatics as they searched their warehouse looking for the aquarium I wanted with a blue back. They stopped making these a while back but they found one for me! I absolutely love this aquarium & I can honestly say that Tyler provided THE best customer service I have ever experienced from an online vendor. He told me from the start that he would stay with me from start to finish & he did. He was always there to promptly answer any questions or concerns I had. I can’t say enough about how happy I am with my purchase!

Piece of Art

I was looking for rimless peninsula aquarium to upgrade my 80 Gallon and my 70 Gallon mixed coral reef this year, but had a really hard time finding it because of the coronavirus. So I purchased a ProStar 230 Peninsula from Two Tides and I’m glad I made the right choice. The 3/4” low Iron glass display tank and large glass sump and light weight white stand is just beautiful as a piece of art. Tyler is extremely helpful and responsive and made the process easy and stress free. Everything arrived very well packaged. When we were setting up the tank, we couldn’t believe how easy the setup was with no issues what so ever. If you are looking for a high quality aquarium I highly recommend this company.

Absolutely beautiful fish tank and customer services

I am very happy with my order. The tank is very beautiful of out the box and it was well packaging with feel very safe from shipping damage.

Custom services from Two Tides Aquarium Supply was excellent. I have communicated with Tyler who had assisted me throughout the process from ordering the tank through shipping process, and what to expect on delivery day.

I am highly recommend anyone who want to get a new aquarium, to purchase from Two Tides Aquarium. Best to look for Tyler, he is a very helpful and pleasing person to contact if you have any question. I am glad that I have met him and definitely I would buy again in the future from Two Tides Aquarium supply when I need another fish tank and any other aquarium supply that I may need.

Thank you very much for a beautiful tank.

Regards,
James

Great Customer Service

I am very pleased with not only the product I received but the service that came with it. Tyler was in constant contact with me throughout each stage of the process. He answered all questions I had and was even able to provide me with links to plumbing parts I needed for the build. We had a small hiccup with shipping (carrier's fault not Two Tides) but Tyler was able to update me throughout the day. Tyler genuinely cares about his customers and I would recommend the company to anyone looking for their next show room tank!

Great unit

Makes water quickly. Very happy with the unit so far. Pump is quiet, runs great. Finally decided to get a good rodi system. This one has exceeded my expectations way better then any other unit that I've had before. TwoTides Aquarium supply shipped it fast and couldn't be happier with this unit.
