Built Different. For Reefers.
We're reefers who got tired of expensive, incomplete kits. So we built something better.
Order today and your kit ships out within days — not weeks. We keep kits in stock and ready to go so you can start your reef without waiting.
We cut out the middlemen and build kits in volume. You get a professionally curated, complete reef setup at a price that makes competitors look expensive.
Every item in our kits has been hand-selected and field-tested by experienced reefers. No filler, no guesswork — just gear that actually works in a reef environment.
Our team is made up of real reefers based in the US. Whether you have a setup question or a warranty issue, you'll talk to someone who actually keeps a reef tank.

Let customers speak for us
Great tank for a great price! SeaCardinal was very responsive. The tank, stand, and all the goodies were packed very well- way beyond my expectations! Had some communication issues with the shipping company, but the delivery driver was very nice and professional.
Great unit it makes pure water very fast . The pre assembled shut off and flush valves were a huge plus
Aquarium itself is beautiful. I would recommend the upgraded light as the standard one I couldn’t get to work. The heater is rated for freshwater only. Keep that in mind if you plan on a saltwater aquarium. The mesh lid kit. I wouldn’t recommend. Get one custom made or purchase one to build with actual instructions.
I am very impressed with the entire setup. For the money I spent, I feel I received a great Nano system for setting up a reef in my office. I highly recommend purchasing this tank.
So Far so good, everything seems good quality and like the design and appearance of the tank. Have not started it up yet, still gathering some other supplies.
this is my first salt water set up and honestly im super happy with everything. all the equipment seems nice. just a heads up the stand is alright but i generally like something a little bit more robust. i was missing the filter sock holder from my order, so i went and ordered another one but also emailed the support, i got response in under 15 mins, that order ended up canceled and got a replacement shipped out.
Well made , great for the value, won't break the bank and has everything you need .
Received about 3 weeks ago Just had time to unpack I feel it was packaged very well. Will try to set up this week and let you know
