Add a touch of whimsy and vital aeration to your water garden with the TotalPond Turtle Spitter. Aeration is the infusion of oxygen into water. It sets the stage for a healthy aquatic environment for fish and plants. To use the spitter, firmly connect tubing from your pump's outlet to the inlet at the back of the spitter. The spitter inlet fits with 3/8 in. and 1/2 in. ID (inner diameter) tubing. For the best results, pair this spitter with a pump between 70 GPH to 400 GPH. This spitter is supported by a 90-day manufacturer warranty.
