Set up was easy and the tank looks great in my living room. The filter and skimmer work well together, keeping water clean and fish active. I’ve had it for three months and haven’t had any issues with water quality.

Great value for the features included. The cabinet is sturdy and the tank maintains stable water conditions. My clownfish and tang are thriving after a month.
