Review: Good quality
Review: Cool micro reef tank but not as advertised - The tank itself is super cool. Has some blemishes but that could’ve been overlooked. After unboxing, it came with a light that was not advertised, and is only 5 watt blue only led. At $169+ which I thought was a bit steep to begin with, I don’t want to go and have to buy another light. Overall is super cool micro reef, but pretty pricey and not what’s advertised

### ⭐⭐⭐ Cool micro reef tank but not as advertised

### ⭐ Not worth the cost. Find an alternative.
*by D***N on March 7, 2025*

Arrived with one outlet tube snapped off, needed to reglue it in place. Light smaller and cheaper than pictured. Clearly a return that was repackaged based on state of box and internal packaging and wrapping. Look for an alternative and don’t buy this.
