Hey T good of you to join us
Teresa... I would do another 50 if your tap is at 10. I would keep up a once a week schedule.
Looks to me like you are going to be targeting about 25 - 30 ppm NO3
after the water change. I would do this by using Chucks calculator and making a stock solution of KNO3. Test your tap at water change, subtract that from your target, divide by 3, and dose that amount every other day.
Target 30 ppm NO3
Tap 10 ppm NO3
Target becomes 20 ppm dosed three times a week or approx. 6.5 ppm each dose. Water change on Sunday 50%; dose 6.5, Tue dose 6.5, Thur 6.5, on the days in between dose 10 ml of Flourish. Keep the CO2 cranked!

Is the controller off line? Looks to me like your pH could drop to 7.2 to give you decent saturation of gas.
Your PO4 could probably go to 2 ppm. same type stock solution of KH2PO4 targeting and dosing on the days you dose NO3.
I am concerned that there will not be enough potassium (K) from the (K)NO3 and (K)H2PO4 to get you to 20ppm. You can do the math using Chuck's Calculator.
If you come up short on K, go to the grocery store and buy some "Nu Salt" or salt substitute. Look at the label, it will be KCL (potassium chloride), with a little non caking agent thrown in. This is a good source for potassium. The calculator has KCL included for you.
Dose the K the same day you do the KNO3 and KH2PO4
Make Sense to you?
Yours in Stock Solutions and Water Chemistry LOL!!
