- Lowest true turnkey cost: $1,899 base, or $2,279 with PopBloom lights and lid — vs ~$2,450+ for IM and ~$2,740+ for Waterbox once they're reef-ready.
- No hidden surprises — lights, lid and RODI are clearly listed as add-ons.

I love it, I haven’t used the protein skimmer yet because it’s not cycled yet. I’m always waiting for the heater because you guys forgot to include it but otherwise I think the quality is great. I also recommend it to the aquarium store I use and they put in a wholesale application to you guys.
Amazing, affordable, all inclusive setup! 🙌🙌
Extremely sturdy and well made. The best lid that I have ever had.
Shipping was amazing, the tank was securely packed in a compressed board box with hinges and locking mechanisms. All items were shipped intact and not damaged.
Awesome, all in one Seahorse Tank. All inclusive!🙌🙌
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.
Love it!
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
