Any damage to a powercord on a submersible pump is not repairable and is a safety hazard. Most impellers can be replaced but check with Customer Care to be sure you get the exact replacment. If your pump is tripping your GFCI outlet that usually means it is leaking voltage into the water and is a safety hazard, you should remove the pump and replace it immediately as this type of failure is not repairable.
You should cover about 60% of your pond surface with floating plants and plants with floating foliage. Too much light penetrating the water surface causes an overgrowth of algae. In addition to blocking UV light plants compete for the same nutruients in the water as algae.
Fish and other biological activity slow down drastically once water temps drop below 50 degrees F. You can continue to run pumps for water features like fountain nozzles and waterfalls as desired but the fish and natural bacteria do not need them to survive below this temperture. In spring time once water temps increase above 50 degrees F start all pumps and filters.
Because they’re made from high-molecular weight polyethylene, preformed ponds resist freezing, and withstand the pressure of frequent freezing and thawing.
Before you purchase your liner, calculate an excess of at least 6-12″ of liner around the entire perimeter of the pond.
EPDM liners stay pliable in very cold temperatures because they are rubber based. EPDM liners are 45 mil think. However, PVC liners are lighter and easier to manipulate because they are plastic based. PVC liners are 20 mil thick.
We never recommend pool and roofing liner for use in water gardens. These materials are not produced with fish safe material and may kill your fish, water plants and other aquatic life.
Usually, green water indicates that too much light is penetrating the water, an excess of organic waste or a high concentration of fertilizer from runoff. An algae bloom in spring when the water temperature rises is to be expected. Use the following steps (in order, not all at once). Stop feeding fish, remove bottom debris, clean bio-filter and pre-filters (using pond water), add plants, add Bacteria / Barley, add UV filtration, Algaecide.
Safety: Locate any underground utilities like electrical or gas lines. Familiarize yourself with local building codes regulating backyard ponds. The National Electric Code requires that a ground fault circuit interupter (GFCI) outlet be used to power fountain or pond equipment.
Elevation: Locate your pond at the higher end of any hill or slope to avoid rain run off which can contain fertilizer and pesticide from lawns.
Debris: Locate your pond away from trees and falling leaves if possibe to minimize maintenance of cleaning the leaves out of the pond. Dead leaves decay and produce toxic ammonia in the pond as well as clog filter and pump inlets.
Sunlight: Aquatic plants like water lilies need at least 6 hours of direct sunlight each day.
