This light is great for my African Cichlid tank!! Shipping was lightning fast too! Will definitely order from aquarium co-op again!

Great light, same great fluval quality as planted 3.0.

I recently started a small saltwater tank but didnt want to invest $500 + on lighting. Coming from the fluval planted 3.0 I gave this a shot and am very satisfied. I can control the marine 3.0 and the planted 3.0 at the same time from the same app. Just some advice this is low PAR compared to the outrageously expensive lights available elsewhere. This is suitable for saltwater tanks with low light corals. Overall I'm very happy with this and every Fluval light I've purchased so far. Aquarium Co-op has very friendly Service as always.

Awesome customer service

Received the light in just a few days however when I plugged it in it did not work. Contacted Aquarium co-op and they responded right away. It was the power supply that was broken.They sent a new power supply as soon as they could (USPS took their sweet time delivering it) and that fixed my issue. I understand that Aquarium co-op has no control over broken parts or USPS not doing their job to deliver stuff on time so that does not affect my rating. I give them 5 stars because their customer service was awesome and worked with me to resolve the issue. All in all 5 stars to Aquarium co-op and 5 stars for the Fluval Marine and Reef 3.0 LED. I highly recommend both. A special thanks to Katie in costumer service and Cory!


I could not be happier with this light! It makes the colors on my African Cichlids POP and glimmer!!! I absolutely love the adjustability through the app, it makes it very simple and even fun. It was shipped very fast and received no damage during shipping. I've ordered from Aquarium Co Op multiple times and will continue to do so!!

Excellent Light!

The full control over the 3.0 Fluval Sea light makes everything consistent and the fish and corals thrive! Will probably buy the planted 3.0 in the near future to see my planted tank thrive as well!
