饲鱼时有病鱼污染了鱼缸水质 在引进新鱼未做处理所造成的 此 情况环节虽小 但 一旦 有病毒发作 处理起来麻烦 啊 如果 单是白点病不用清缸消毒 升温30度 一般一周内 即可病愈 严重的配合小剂量药浴 缸内只要有烂的存在就需要消毒处理了 缸内 或 过滤内 有致命的病菌 清缸消毒是必须的了 过滤材料 全得报废掉 必须从新换 不管 你多大的缸 使用 高锰酸钾 消毒 是饲鱼 最古老的传统方法 话说 高锰酸钾 到现在的这个时代 都算不上是上品的消毒用品了 但用于 鱼缸 消毒 还是可以起到百分之80消毒效果 不完全 计量 稍微大些 正常计量是 不管你多大的缸 以水为 粉红色 为标准 个人认为 紫红色 为好 一般消毒时间为 3~5小时为好 个人认为 时间在长点也无妨 但 高锰酸钾 唯一 缺点 腐蚀鱼缸 消毒后清水洗缸
