Thanks Jeff & Tugg,
Today is water change day. I will soon know if I will continue to use my scales. I intend to test after the change and adjust my parameters by dry dosing using + or - teaspoons and then test again. My results should be close to the calculations. Then when its time to dose again, I will have a new batch made up in PO4 using 43 grams of KH2PO4 in 500 ml of distilled water. I have volumetric lab glassware to measure the water. But this time I will dose only 25% of what Wet's calculator says, in case there is a large error Then I will know from the result whether my large scale is good enough for hobby purposes.
