Koi & Pond Tip of the Day
December 17th, 2014
A dirty filter can cause the flow in a pond’s water feature to slow. If you notice that the water flow appears to have decreased, the filter and pump intake should be cleaned as soon as possible. This will help ensure maximum filtration and if the clog is on the inlet side of the pump, it will help prevent pump damage.
