Gravity Pond filters

Gravity Pond filters - Cozzie's thoughts

Suitable for: Gravity Pond Filters are best for ponds which contain Koi and Turtles. They are also best for large ponds.

What we liked: We have several different brands to choose from, remember you get what you pay for, Cheaper at the top, quality at the bottom.

What comes as standard on every filter: They all have different features, the better quality have foams and features.

Less than ideal: They are not suitable for water features, unless they are mounted at the top.

**This pump has a little too much flow, intalling a water release kit will help reduce some of this flow.
