Why is My Pond is Green?

As a disclaimer, all ponds are different and the following information may vary from pond to pond.

The Overview

In general, a pond will turn pea soup green due to: inadequate filtration, lack of aeration, unbalanced water chemistry, not enough plant life, too many fish, lack of general maintenance, improper climate (ie full sun), and/or deficient good bacteria.

Inadequate Filtration

Wether your buying a professional pond kit or piecemealing your pond together; homeowners often make the mistake of skimping on the important stuff.
You should never undercut the pump size and filtration.
We recommend turning over your pond water three times per hour, meaning if you have a 1,000 gallon pond, you should have a 3,000 gph pump. I recommend doubling your ponds filter; for a 1000 gallon pond, you should have a filter rated for 2000 gallons. I cannot stress this enough. The two things you should never skimp on are the pump and filter.

New Pond / Cleaned Pond

If you have a new pond or did a full cleaning midsummer, there is a 90% chance you will get a pea soup algae bloom two to four weeks after. New ponds or freshly cleaned ponds have little to no established ecosystem; therefore, without enough beneficial bacteria to breakdown access ammonia and nitrite, your pond will have an algae bloom. This bloom will be enhanced by high exterior temperatures especially in midsummer. We recommend starting up your pond in April, thus providing adequate time to establish an ecosystem before the heat of summer. If this isn't an option...boost aeration, increase plant coverage, provide shade, do weekly water changes, and limit fish / fish feeding.

Too Many Fish

Fish produce waste. The more waste, the dirtier the pond. Housing the proper quantity of fish is imperative to maintaining a successful ecological balance in a pond.
