!GLUTTON 评论：这种测试笔的原理是根据测量介质的电阻来判断的 记住：纯水是不导电的 日常的水导电是因为水里很多杂质 所以TDS只能表示水里的杂质 不能代表水的hardness

Snail comment: There are excrement of fish in the fish tank, there are food residues, debris of various filter materials, and the Sanhu tank must maintain high hardness, so there are a lot of substances in the water.The value of TDS is basically meaningless.Luhua Arowana which brand of oil is good&What brand of feed is good for goldfish?$Which country brand is Arowana oil/What oil does Arowana have.What brand of feed do guppies feed?!Why the country can"t help arowana$Which brand is good, Xiwang and Arowana)Which country"s brand is Arowana?%Which country is Arowana Company??
