解密系列：shanhu盐（1）- 种类和优缺点

kmzhq · 发表于 2020-3-25 17:26:48

大部分品牌的盐我都用过，补充一点看法：

1、原材料的纯度，纯度决定了价格。但是食品级和医用级、分析纯的纯度区别不大，毒害性区别也不大。

认可原材料的纯度决定了价格。但不同品牌的盐使用的原材料是不同的，所以价格也有差别。

认可食品级和医用级、分析纯的纯度区别不大。对人来说毒害性区别可能不大，但不认可对shanhu的有害性差别也不大。试过用食品级、医用级和不同品牌的分析纯配滴定液，同一缸shanhu，状态差别很大。

2、原材料的混合工艺，工艺好坏决定了盐的指标是否稳定。但这个是一个水产领域不太care的问题。

事实上，我们可以很直观的就可以理解不同的原材料物理化学特性、密度不一样，在混合的时候一定会产生混合不均匀的现象。

这是一个非常普遍的问题。故而所谓的进口品牌、元素丰富，很可能只是一种心理安慰。比如，国内最热门的所谓进口XX盐之一，号称是来自上古时代几亿年前的深层海水，这已经是完全没有了操守和底线，海友普遍反映其KH波动特别大。既然它的KH波动这么大，那么它是提纯盐还是勾兑盐，就知道了。

实际上，很多盐可以说是几乎所有的水族盐，进口的、中国产的，都存在这个问题。我们不排除国外进口盐可能经过了更多的国内外实践检验，我们也不排除一些中国产的盐知道元素指标稳定是和国外品牌的唯一竞争优势，所以会在这个指标上下功夫。

认可原材料的混合工艺，工艺好坏决定了盐的指标是否稳定。

过去大部分进口品牌盐，特别是那些历史较长的，指标稳定，元素丰富，养高档shanhu和用普通进口盐或国产盐差别很大，当然养普通shanhu或鱼区别很小。但现在有些进口品牌是国内代工，品控不够好，和国产品牌差别就不是很大了。

现在不同品牌的国产盐，养普通yinggushanhu差别也非常大，很容易造成一些品种的shanhu养不活（包括容易养的），我估计是某些微量元素的含量不合适（缺乏或过量）。

海水盐里三大元素是重要，但其他微量元素和痕量元素也重要。不能说

三大元素差不多，盐的质量也就差不多，

特别是要养好、养长和繁殖shanhu。就像有句话说：细节决定成败嘛。

in us , lots of guys use China - made aquarium salt such as XXX and maintain an amazing 大树叉子 tank.
And dragondragon himself uses another China - made salt and also have great performance.
but in general i think aquarium industry is much more developed abroad, products are much more reliable

         More than ten years ago, I went to the United States and Europe, where the products made in China and the products sold in China, even if they are the same model, have great differences in quality. So I feel that Chinese products are very good overseas. I don't know how it is now.
         At the same time, the quality of foreign products sold abroad is different from the same products sold domestically. Of course, foreign prices are still cheap. So Chinese people like to shop abroad. I don't know how it is now.
         I only know that in the sea water equipment, the quality of many foreign products sold in China is becoming more and more unstable, while the quality of products made in China is getting better and better. But there is still a gap with the famous foreign brands.
