ppm(parts per million)就是百萬分率,即1000公升的水含1公克(1g=1000mg)的物質,即1ppm等於1公升的水含1mg的物質,10公升的水加200mg~300mg黃藥,配出來就是20ppm~30ppm。
1%濃度就是100公升的水加1000公克(g)的物質,即1公升加10公克(g)的物質,加鹽0.3%就是100公升的水加300公克(g)的鹽。
ppm is called 1000 liter water included 1 gm of material. So, 1ppm is called 1 liter water contained with 1 gm of material. If the yellow medicine 200 ~ 300 gm included in the 10 liter water, it is called 20 ppm ~ 30 ppm. The consistency 1% is meant adding 1000 gm material into 100 liter water, also meant adding 10 gm material into 1 liter water. Adding 0.3% salt means, adding 300 gm salt into 100 liter water.
金魚保健不求人-換水:每次換1/4-1/2缸水(新水先除氯),夏季每週一次/冬季半個月一次
視魚病狀況換2/3缸水+0.3%~0.5%粗(食)鹽
換水不洗濾材,洗濾材用缸(舊)水
白棉至少兩層,過髒換上層,新綿放下層
