Pond Vac
Questions & Answers

Questions & Answers
Will the Pond Vac System suck in my fish?
Our experience shows that the vibration and sound of the motor keeps the fish away. In five years of working with this design, we have never found a fish in the net when cleaning.
What size vacuum should I order for my pond?
We recommend the following;
1/6 HP, 1700 GPH for ponds less than 5000 gallons.
1/2 HP, 1900 GPH for ponds between 5000 and 10000 gallons
3/4 HP, 2900 GPH for ponds between 10000 and 15000 gallons
1 HP, 3200 GPH for ponds between 15000 and 20000 gallons
1 HP SS, 3500 GPH for ponds between 20000 and 25000 gallons
1.2 HP, 3750 GPH for ponds over 25000 gallons
Do all of the pond vacuums use the same bags?
No, the bags are sized in proportion to the size of the pump.
We design to provide a flow rate that is effective at separating the solids without restricting the flow.
I am a small female. Can I handle this system by myself?
The larger the bag, the more water weight that will have to be handled.
We recommend the use of the two smaller sizes to make handling easy.
A person could always use two systems running in separate areas of the pond to double the cleaning rate. This would require more handling of lighter systems.
What are the bags made of? How long do they last? Can I make/repair my own?
The inner bag is made of a fabric backed fleece. The outer bag is heavy nylon mesh. Bags can be self made or repaired, but we recommend having them sewn by a canvas or shoe repair shop. Home machines can't make a strong enough stitch to hold the great pressure built up in the bag.
How long will these systems last?
We have systems that have been in use for five years. You can extend the life of your system by washing and drying the bags before storage and removing the pump from the pond when not in use. PH levels above 7.5 or below 6.5 can damage the metal motor parts if left in the water.
The bags can be damaged by dragging over rough surfaces.
Careful handling will increase the life of your pond vacuum.
How long should the vacuum be left in the pond?
The vacuum should always be monitored while running. The danger is that the bag could develop a hole and the water spout from that hole could drain your pond very rapidly. Check the bag for hardness every ten minutes. Use a broom handle to thump the bag. Once the bag becomes rigid and hard to the touch, it needs cleaning. If left too long, the internal pressure could cause the bag to burst.
What is the fastest method to clean my pond?
The quickest method is to use a pool net to remove heavy debris, then insert the vacuum. Continue to stir the water with a broom or paddle when you see the dirt is settling. The vacuum works best when the dirt is suspended and passing near the area of the vacuum pump. Move vacuum as necessary.
Will the pond vacuum remove algae?
The Pond Vacuum will remove suspended algae. For algae attached to surfaces, mechanical removal is necessary. String algae can be removed by using a dowel rod mounted in a portable electric drill. Roughing up about one foot of the end causes the strings to wind up on the dowel when immersed into the pond. Cut the ball of algae off the rod and start again.
