I bought the 300 model for my small tank and it provides just enough flow without being too loud. The pump is compact and fits well in the corner. Works reliably and has been running for over a month without issues.

The 600 model gives a strong current in my 100-liter tank. I appreciate the adjustable flow. It’s quiet during operation and fits neatly in the setup. Only downside is the initial setup took a bit of time.

Used the 2100-5000 in both freshwater and saltwater. It’s durable and performs well in both environments. The included accessories make it easy to set up and modify for different uses.
