The Summer Pond Revisited

Keep Your Cool!

Keeping your pond cool and oxygenated should be your primary focus during the hot summer months.  The warm weather has a dramatic affect on oxygen levels in your pond - the warmer the water, the lower the level of dissolved oxygen.  Low oxygen levels can lead to fish kills, increased algae growth, and a reduction in beneficial bacteria resulting in an increase in ammonia, nitrites and nitrate.

A relatively easy way to keep your pond cool is to add surface plants to the pond (aquatic plant products found here).  If you have fish, a good goal is to have 70% of your pond surface area covered during the hottest weeks.  You can add floating plants, such as water hyacinth, water lettuce, and water chestnut.  Another option is to add a floating planter, or floating planting baskets, which provide much more plant variety.

Also consider using a pond tint.  These all-natural products act as a "sun block" for you pond - keeping temperatures lower and inhibiting algae growth.  A great choice is the Pond Logic Plus (that includes the PondClear clarifying agent) which comes in either Nature's Blue or Twilight Blue Tint. 

A bottom aeration system is extremely effective in cooling the pond water and increasing oxygen levels thereby ensuring healthy pond life, promoting beneficial bacteria growth, and lowering toxic gases and ammonia by promoting gas exchange.

Oase and Airmax Eco both have fantastic bottom aeration kits.  We really like these kits as they are truly the only "plug and play" systems available for ponds of all sizes (not just small ponds).
