Pond Salt Crystal Clear Vanish dechlorinator
Aquarium Pharmaceuticals evaporated sea salt.

Koi and other pond fish normally have a balance of electrolytes in their body. Chloride cells in the fish gills remove electrolytes (calcium, chloride, magnesium, potassium and sodium) from the pond water. The lack of electrolytes prevents fish the ability of oxygen intake as well as carbon dioxide and ammonia release (osmotic shock). Pond salt provides the essential electrolytes that fish need to help reduce the risk of osmotic shock.

Pond salt reduces nitrite toxicity. Overcrowding of fish and overfeeding lead to elevated nitrite levels. This generally happens in new pond environments. Nitrites enter through the gills and prevent the blood from carrying oxygen resulting in nitrite toxicity.

1/2 gallon treats 1,000 gallons.

Koi Vital Ammo-Lock 2
Tetra Pond Koi Vital creates "natural" water conditions for fish to thrive.  Formulated to replenish essential trace elements and vitamins.  Increases the fishes' energy level and sexual activity.  Treats 2500 gallons. Use Ammo-Lock 2 to eliminate the toxic effects of chlorine, chloramines and ammonia that may exist in pond water. Uneaten fish food, decomposing algae and plants, and fish waste create ammonia. Ammonia, which is a colorless and sometimes odorless chemical, is the #1 killer of pond fish.

Ammo-Lock 2 detoxifies harmful ammonia levels that can result from overstocking and overfeeding of fish. Although ammonia remains in the pond, with proper treatment the levels will neutralize and convert the ammonia to a non-toxic form that is safe for aquatic life. This non-toxic form becomes a nutrition source for the biological filter which converts the ammonia into nitrite and then to non-toxic nitrate.

Ammonia levels will test positive when using Ammo-Lock 2 but levels will drop as the filter breaks down the converted ammonia. 16 ounces treats 1920 gallons.

pH Down 16oz pH Up 16oz

pH Down pH Up
Aquarium Pharmaceuticals pH Down slowly adjusts pH of pond water without harming delicate pond fish or pond plants. Phosphate free, pH Down will not promote algae growth.

What is pH?

pH is the measure of pond water acidity. A neutral pH reading is 7.0. A pH higher than 7.0 is alkaline, lower than 7.0 is acidic. Acid rain, mineral leaching, soil runoff decomposing plant and fish waste can cause unacceptable pH levels. Even tap water used to fill fish ponds and garden ponds can cause extreme pH levels. Avoid pH levels below 6.8, which will stress pond fish and suppress biological filter activity, and pH levels above 8.0, which will hamper the ability of most plants to absorb necessary nutrients. pH should be raised or lowered by no more than 0.5 units every 24 hours. Use 1 teaspoon for each 50 gallons of pond water.
