Question for those of you using meters with your mega crop - what TDS scale are you using?
Im asking because I just compared my readings using an Apera PC60 meter to the TDS numbers on the mega crop website feeding instructions, and my readings are way higher than what the webpage suggests they should be. I just checked and my meter came set to the 700 scale. Actually the TDS compensation factor came pre-set to 0.71
I have some feed water mixed at aprox 5.5 to 6 gm per gallon and it was reading 1310 PPM. The website says it should be in the 500 to 546 range. My water starts out at least 120-180 PPM, so I should be seeing 620-720 or so. So Ive been getting reading almost twice the calculated values from the website.
So, I changed the compensation factor to 0.50 (the 500 scale on some meters) and my water is now reading 701 PPM - which agrees close enough with the website's calculated values.
Anyway, Im curious what scale you guys are using and what your TDS readings are at the dosage you are using compared to the website values.
I know the mega crop guys are working on a meter reading chart, and Im also curious what scale they are using.
