## 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
