This is an easy to service filter and filter media is readily available from various pond suppliers. A bit small for the size pond we have but works well in fall through winter. Need to service more often in late spring and through out summer. Best to purchase 2 so you can rotate one out and service the other when convenient. Typically service about every 3-4 weeks for our pond (est 3000 Ga). Have tried to purchase additional filters but Overstock no longer carries them.
I am using this pump for water flow in a garden fountain. The description indicates a flow sufficient for a 24" rise. It is true that the pump is strong enough to raise the water 24", but only a trickle is produced. I was looking for a stronger flow. Having nothing else to use, I will continue with this until I find a stronger pump. Very difficult to find what you need when electricity measures in gallons per hour and solar measures in Watts.
