The cause, harm and treatment of abnormal ph value. It is necessary for us to use an industrial PH meter to check the pH of the fish pond at any time and make different adjustments according to different situations.
1. The reason why the pH is too high or too high.
(1) There is a certain amount of algae in the new water, but the water quality is not stable and tends to be high.
(2) The water body rich in blue-green algae is very strong due to photosynthesis. By about 5 o'clock in the afternoon, the pH will often rise to above 9.5.
(3) The ph value of water contaminated with alkaline substances will also be high. Symptoms of fish alkalosis: irritated and maddening; a lot of mucus on the body surface can even be pulled into silk; the cap is corroded and damaged, and the crotch is secreted a lot; the water body is alkaline, generally the pH value is greater than 9; Many dead algae and dying algae cells.
2. The reason why the pH is low or too low.
(1) The pond water with longer breeding time has low transparency, low pH value, and even less than 7.5 in the afternoon.
(2) It is contaminated by acidic substances. Symptoms of fish acidosis; body color is obviously white; aquatic plants appear brown or white; water body transparency increases significantly; water body is acidic, generally ph value is less than 4; water body has algae cells in many dead algae and dying.
