Aquarium Pharmaceuticals Freshwater Additives/Supplements

Aquarium Pharmaceuticals pH Down®
Aquarium Pharmaceuticals pH Down® 4oz Lowers pH and makes aquariums more acidic. Fast-acting, colorless and easy-to-use.

pH Down is a liquid pH lowering product for freshwater aquariums. pH Down lowers pH by neutralizing carbonate hardness in the water.

Adjusting the pH to the proper level will improve fish health, disease resistance, coloration and breeding. While many common aquarium fish will live in water with a pH range of 6.8 to 7.5, a pH of 7.0 is ideal for a community aquarium containing a variety of freshwater fish. Live bearers like mollies and swordtails prefer a higher pH of 7.2-7.6. Acid-loving fish such as angelfish and neon tetras prefer a lower pH of 6.5-6.8.

Each dose of pH Down neutralizes some of the carbonate hardness and lowers the pH. The pH may rebound up to the original pH if the carbonate hardness is high. Several consecutive treatments with pH Down may be necessary to lower pH, but if there are fish present in the aquarium, the pH should not be changed more than .2 in a 24 hour period. The number of doses required to lower the pH will depend on the carbonate hardness level and the desired pH level. An aquarium with low carbonate hardness may require one treatment with pH Down while an aquarium with a high carbonate level will require several.

Aquarium Pharmaceuticals pH Up®
Aquarium Pharmaceuticals pH Up® 4oz Raises pH and makes aquariums more alkaline. Fast-acting, colorless and easy-to-use.

Purpose and Benefits:

pH Up is a liquid pH raising product for freshwater aquariums. By neutralizing acidic substances in the aquarium, pH Up effectively makes the water more alkaline. The pH may rebound down to the original pH depending on the level acid in the aquarium. Several consecutive treatments with pH Up may be necessary to adjust pH to the desired level, but if there are fish present in the aquarium, the pH should not be changed more than .2 in a 24 hour period.

While many common aquarium fish will live in water with a pH of 6.8 to 7.5, a pH of 7.0 is ideal for a community aquarium containing a variety of freshwater fish. Live bearers like mollies and swordtails prefer a higher pH of 7.2-7.6. Acid-loving fish such as angelfish and neon tetras prefer a lower pH of 6.5-6.8. Making a partial water change (10-15%) will also remove some of the acids and help stabilize the pH. Adjusting the pH to the proper level will improve fish health, disease resistance, coloration and breeding.
Aquarium Pharmaceuticals Proper pH® 6.5
Aquarium Pharmaceuticals Proper pH® 6.5 Automatically sets & stabilizes pH at 6.5. Removes chlorine & detoxifies heavy metals. Great for Tetras, Discus, Angels. Contains Aloe Vera and electrolytes to reduce fish stress. Use when setting up an aquarium or changing water.

Purpose and Benefits:

Proper pH 6.5 is a pH adjuster and stabilizer (buffer) for freshwater aquariums. Proper pH 6.5 neutralizes chlorine, detoxifies heavy metals, and adds electrolytes to the aquarium. The product also contains Aloe Vera, a proven natural stress reducer and healing agent for tropical fish.

Proper pH 6.5 is formulated to lock the pH at 6.5. Buffers compensate for fluctuations in pH, automatically adjusting the pH to the predetermined level. Proper pH 6.5 will lower or raise the pH until 6.5 is reached. pH will not rebound to the original level. It may require more than one dose to adjust the pH. This is because carbonates (KH) in the water work against pH adjustment.

Aquarium Pharmaceuticals Doc Wellfish's Aquarium Salt
Aquarium Pharmaceuticals Doc Wellfish's Aquarium Salt 16oz All natural salt, made from evaporated sea water, promotes healthy gill function, reduces stress and loss of electrolytes. Used to improve the efficiency of medications and reduce the harmful effects of nitrite.

Doc Wellfish's Aquarium Salt is made from evaporated sea water. This all-natural salt is intended for use in freshwater aquariums to add natural electrolytes, improve gill function, and reduce fish stress. Freshwater fish actively maintain a natural balance of electrolytes in their body fluids. Electrolytes such as potassium, sodium, chloride, calcium, and magnesium are removed from the water by chloride cells located on the gills. These electrolytes are essential for the uptake of oxygen, and the release of carbon dioxide. The lack of electrolytes can cause serious health problems for fish. During periods of disease and stress, healthy gill function is disturbed. This can lead to loss of electrolytes and osmotic shock. Osmotic shock reduces the ability of the gills to take up oxygen and release carbon dioxide and ammonia. Aquarium Salt reduces the risk of osmotic shock by replenishing natural electrolytes fish need.


Aquarium Salt can also be used to reduce the toxicity of nitrite to freshwater fish. Nitrite (NO2-) enters the gills and prevents the blood from carrying oxygen, resulting in nitrite toxicity (methemoglobinemia). Aquarium salt will temporarily block the toxic effects of nitrite until water quality can be improved.

Aquarium Salt contains no artificial additives, sugar and, unlike table salt, no artificial color. It is made from evaporated sea water, which contains the following beneficial electrolytes needed by freshwater fish: calcium chloride, magnesium chloride, magnesium sulfate, potassium chloride, and sodium chloride.

Purpose and Benefits:
  • Once added to the aquarium, salt does not evaporate and is not filtered out! After making the initial treatment with Aquarium Salt, add more salt only when making a water change. If, for example, you remove five gallons with a water change add only enough salt for five gallons.
  • Add one rounded tablespoonful for every 5 U.S. gallons (19 L) of aquarium water. To treat goldfish bowls add ½ teaspoonful for each U. S. gallon (3.78 L).
  • Aquarium Salt may be used as a short-term bath to treat external parasites (Tricodina, Ichthyobodo, or Epistylis). Dissolve 2 ½ cups (370 g) for every 10 U.S. gallons (40 L) of aquarium water. Carefully place the infested fish in the container for 5 to 10 minutes, and then put the treated fish back into the aquarium. The bath may be repeated in 24 hours if necessary.
Compatibility:
Aquarium Salt can be used with tropical fish, goldfish and koi. Aquarium Salt will not change pH. Aquarium Salt should not be used as a substitute for marine aquarium salt.
