  • Easy to use.

Great addition to our pond. Worked well as we upgraded our waterfalls and filter system.

  • Good for price.
Material Type: 16" Waterfall Style: Without Pump
I installed so it overhangs the wood fram for a fish pond. It’s a simple, efficient design and works well. It needs to be supported well, since it’s a hard plastic which will crack if stressed.

  • Stable and pretty waterfall
Material Type: 16" Waterfall Style: Without Pump
Needed to buy this, a pump, and some tubing. 1.5" This setup works pretty well! The water started filthy after being stagnant in the summer for a month after my last filter died, but after two days the top two or so inches are clear again. Not all of it, but I'm sure it will continue to improve as the good bacteria comes back and the filter gets established. I fit a few little plants in the top of the filter and it looks nice. ... show more

  • 2 star packaging, 5 star waterfall
Material Type: 16" Waterfall Style: Without Pump
Great waterfall design, easy to assemble. Needed over 20 minutes to remove three double-sided tape strips with a razor-isopropyl alcohol combination. The tape deserves six stars, please post the brand. Waterfall had straight sheet flow, and is a great aeration feature.
