| my readings
Sorry its taken so long to reply but i work very long hours,as i said before i do use one but i do not trust the reading,mine is made by american marine inc.
If you read koi kichi 2 it states that between 300 and 475 are the best figures, is my pond between these two i doubt it, but thats what the meter says!
I also own 2 hanna tds meters do i believe the figures nope, I take them with a pinch of salt.If i add up my gh and kh readings they do not match what the meter says.(i bought my second one last week) or are the gh and kh test kits out.
I also have lots of temperature gauges they also read differently which one is correct ?If i had an old fashioned mercury temp gauge i would be more inclined to believe that one though. |
