据科学测定,鱼塘中酸碱度适当,pH值为7.0～7.8时,鱼类食欲旺盛,生长良好。但当pH值在6以下,或超过10时,必须采取有效方法,及时进行改良。其改良方法如下。1.以水压酸就是用抽水机抽出酸性池水,注入新水,提高水体pH值。经反复换水,就可使鱼塘水体达到适宜酸碱度。2.以肥改碱就是 According to scientific tests, fish pond pH is appropriate, pH value of 7.0 to 7.8, fish appetite, good growth. However, when the pH value of 6 or less, or more than 10, we must take effective ways to promptly be improved. The improvement method is as follows. 1. To acid pressure is to use the water pump out of acidic water, into the new water, improve water pH. After repeated changes of water, you can make the fish pond water suitable pH. 2. to change the base is fat
