## Questions & Answers

**Q: What size pond (in gallons) is this suitable for?**
A: My pond is about 4000 gallons with waterfall but when temps get hot for a long period of time a waterfall just doesn't produce enough oxygen. This is just right size for my pond. Hope this helps. Can never have too much oxygen

## Customer Reviews

### ⭐⭐⭐⭐⭐ Bye bye algae bloom
*by G***W on June 8, 2020*

Awesome addition to my koi pond. Had a bloom of algae when the water warmed and the extra oxygen produced from the Stone got it in check.

### ⭐⭐⭐⭐⭐ Great product
*by K***N on September 9, 2014*

Speedy arrival, and product highly recommended , very pleased

### ⭐⭐⭐ This airstone is recommended by Amazon as an accessory for the pond bubbler ...
*by D***H on December 1, 2015*

This airstone is recommended by Amazon as an accessory for the pond bubbler I bought. But it is NOT suitable to fit the hose gauge on that bubbler. Beware. This stone seems like a good one but it does NOT suit the Danner AP-20 bubbler.
