How to Lower pH in Aquarium – There is nothing worse than arriving at your house and finding that the fish you had in your carefully maintained fish tank has died. The fish can be quite fussy about their habitat, so it is important to know their needs and make sure they are given the right living conditions so that they can thrive. The pH of the water is an aspect of fish tank maintenance that is extremely important if you want to keep your fish alive. The pH is the measure of the acidity of a substance. It is measured on a scale ranging from 1 to 14, with 1 being the most acidic end and 14 the most basic (or least acidic) end. Pure water is neutral, which means it has a pH of 7, but the impurities can alter its neutrality condition and make it slightly more acidic or basic.

Maintain a constant pH. It is important to maintain the pH consistency in an aquarium, even if it is not exactly the pH that the fish needs. In general, fish can survive in a range of pH levels, as long as your tank is close to the optimum pH and you keep it regulated.

Check the hardness of the water in your aquarium. The water in your tank has minerals that naturally dissolve in it, and these act as buffers to maintain a stable pH. These minerals contribute to the hardness of the water. If your water is not hard enough, which means that there are not enough dissolved minerals, any measure you take to adjust your pH will only be useful in the short term.

Perform a routine maintenance of the aquarium. The waste resulting from respiration and elimination of the fish releases phosphates in the water, which lower their pH. Although it is not usually necessary to lower the pH of aquarium water, allowing the accumulation of waste could greatly decrease the pH of your tank water. It is important to clean the filters routinely and empty the gravel each time you make a change of water.

Change part of the water in your tank regularly. The water in your tank loses the ability to buffer and maintain an appropriate pH over time, as the acidic and basic ions become neutralized. You can not change all the water in your aquarium in each cleaning since this could affect your fish, but doing a partial replacement with fresh water will incorporate some ions and will restore your buffer system (better known as buffer system), maintaining an appropriate pH.

Use floating wood in your tank. Floating wood contains tannins that filter into the water and lower the pH. It is important that you buy floating wood that is safe for use in aquariums and that you wash it properly with water and brush before using it. Do not use chemical cleaners or soap since you could poison your tank.

Include peat moss in your aquarium. Peat moss is acidic by nature, so incorporating a small amount will lower the pH of your water. It is important to start slowly and add to small amounts so as not to lower the pH as much. You can also add it in the filter or place a little in a mesh bag and put it under the gravel.
