The filter works well with my 50-gallon tank. The adjustable uplift tubes help with water flow, and the fish-saver elbow makes cleaning easier. No leaks after a month of use. Strong build quality.
Penelope Hughes –
Fits my hexagonal tank perfectly. The multi-plate design allows good filtration. I used the flow-thru option with my power head and noticed better water movement.

Easy to install and maintain. The plastic doesn’t crack even after several months. The discard-a-stone feature helps with cleaning without disturbing the fish.

Good filtration performance. Works well in a 45-gallon tank. The separate plate option is useful when I want to adjust flow.
