鱼缸长时间放置,总会浑浊,如果加几个过滤器,就能够解决这个问题。但是过滤器比较贵,这里给大家介绍一种廉价而有效的过滤方法,廉价到没有一个工厂愿意生产,但又被证实是最有效的。那就是沙滤,不是流沙过滤器,就是简简单单的沙滤,自来水厂和水产养殖场一直在用的。水经过沙滤后,浑浊度可达5m g/L以下,色度有所降低,抑留细菌率为80%~90%,能除掉蠕虫卵和阿米巴原虫(自来水厂标准)。 Tanks placed for a long time, always cloudy, if you add a few filters, we can solve this problem. But the filter is more expensive, here to introduce a cheap and effective filtering method, cheap to not a factory willing to produce, but has proved to be the most effective. That’s sand filtration, not sand filtration, simple sand filtration, and water utilities and aquaculture farms. Water after sand filtration, the turbidity of up to 5m g / L or less, reduce the color, retention bacteria rate of 80% to 90%, can get rid of worm eggs and amoeba (water plant standards).
