Benefits:

  • Extremely affordable and efficient way of polishing water - just add flow
  • Removes yellow and blue tint to aquarium water, dramatically increasing visual appeal and PAR impact of aquarium lighting
    • Studies have shown unpolished, yellowed aquarium water reduces lighting effectiveness and PAR by 15-25%
  • Absorbs excess medications from previous disease treatment
  • Varied Pore Size Structure effectively traps a wide variety of aquarium pollutant molecules
  • Peak Absorption Capacity maximizes longevity of useful life, making carbon changeouts less frequent

Two Tides Advisory:

Activated carbon has been used for decades in water treatment and purification as a natural way to filter out very fine molecular particles that tint and slightly cloud water to hinder light penetration, as well as negatively affect chemical balance. In an aquarium setting, carbon is also extremely useful to remove excess medications after treating for a potential or apparent aquatic illness.

REEF SPEC Activated Carbon is a very solid upper middle ground option for those that want the instant clearing and polishing effects of higher end carbon, while still at a manageable price point for most hobbyists. We see it as a good gateway into upper echelon builds to experiment with the difference between budget and premium chemical filtration.

We advise using this media with a Carbon / Media Reactor if space and budget allows. This will ensure that water will be forced into every pore of the media, which will allow the entire useable surface area of a square football field per teaspoon of media to be utilized. Not only will this help us get the most bang for our buck in terms of the largest amount of chemicals being filtered out for the given amount of carbon, but will also give us a slight edge in longevity, as chemicals forcefully flow through the entire pore structure, not just stopping at the outer edges due to improper flow, and our carbon will effectively filter for longer.

If this carbon is used in a Filter Bag, it's no big deal. Simply fill the bag 60-80% full of carbon, tie it off, and place in a high flow area of your filtration system. Just keep in mind that most likely the entire surface area of the carbon will not be used, but this isn't so bad as it is relatively affordable to replace anyways.

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.
