couple of questions
1. my r/o unit produces water that reads 0 ppt and 0ms on the hanna combi meter and has a pH of 8.5 , any suggestions for what is in the water making it so alkaline?
2. How do you equate an EC or TDs reading with hadness , i seen a suggestion of 17ppm as being equivalent to 1 kH (or poss gH) does that seem about right
and would that make my thing that 0.17 ppt would be roughly the same ?
sorry :roll: my maths is a decimal place out , scratch that question
can i still say 0.02 is roughly 1 kH on my meter?
3. until what age,size can the sex ration of fry be manipulated
Thanks
andrew
