Pet Product Review

I have several horses so a 100 gallon tank is just about the right size for most of the fields. I have had one tank that was my grandfathers tank for his cows - the tank is probably 35 years old. The only problem I have noticed with the tanks I have purchased in recent years it that they so seem to begin to leak in about 5 to 7 years after purchase. I have one or two rubber tanks but I tend to think the Galvanized tanks keep water cooler and fresher - probably all in my mind!!!
