What size weights to use for anchoring a pond fountain

What size weights to use for anchoring a floating pond fountain or lake aerator:

It is so important to follow these guide lines for anchoring a pond fountain or decorative aerator when using weights. If not done properly, the force of the motor can cause the unit to spin and pull the float down under the water, impeding the spray of the nozzle. Here is a chart of the minimum weight for each anchor according to the size of the floating fountain.

Secure a 3/8" or thicker nylon anchoring line to each of the two attached eyebolts on the shaft of the unit, or thru the holes on each side of the float. Make sure lines are long enough to extend outwards, 10 - 15 feet apart for pond fountains, for lake aerator 20 - 25 feet apart at a 45° angle to the pond or lake bottom.

Size of display aerator or decorative pond fountain:

1/3 HP - 20 lbs each

1/2 HP - 25 lbs each

3/4 HP - 25 lbs each

   1 HP - 35 lbs each

1.5 HP - 45 lbs each

   2 HP - 45 lbs each

   3 HP - 55 lbs each

   5 HP - 75 lbs each

At this point, your display aerator or pond fountain can be floated into position in your pond or lake. Once you have decided on a suitable location for the fountain to be placed, simply attach a boat anchor, concrete block, or similar weighted item to each of the two nylon lines. Once attached, place those anchors at the bottom of the pond spaced appropriately for the size unit.
