If you own a pond, you need to have a relationship with Jones Lake Management. Please notice I did not say you should check into, give them a call, or even state it as a suggestion. At least a half a dozen people on my street have ponds and nearly all of them are serviced by Jones. Whether you're looking to stock your pond or keep it clear and attractive throughout the year, they are absolutely the company to call. Every employee has a college degree in a related field regarding aquaculture. They are all experts. I have never been able to stump them and nothing more than a telephone call and a brief description is usually enough for them to diagnose an issue with aquatic weeds or other trouble with the pond. The absolute best part about this company is that they will not sell you things you don't need, on the contrary they will stop you from making mistakes even if it means buying less from them. They are in fact one of the most honorable businesses that I know of today. Again, I strongly recommend visiting one of the many locations and picking up a catalog. You will not be disappointed if you do.
