5/8/2011 Scheduled Watering - Reservoir Log

Reservoir poured on 5/2 with:

- 40 Gallons Tap (PPM = 070, up from 045)
- 6000 mg Vitamin C
- 1 Tablespoon Ancient Humate
- 50 ml Molasses
* PPM = 115

Reservoir Further Tended on 5/8 with:

- 20 ml Silicon
- 20 ml Microblast
- 10 ml Cal-Mag
* PPM = 150
- 1.5 TBSP 20/20/20
* PPM = 208, pH = 6.8
- pH adjusted to 5.5

* FINAL READING BEFORE APPLICATION : pH = 5.5, PPM = 225

Notes & Analysis:

1) I suspect the PPM reading is too high, will aim
for PPM = 125-175 during the next watering.

2) In order to lower PPM and chemical composition overall,
I will be reducing future Vitamin C levels to 500 mg per 40
gallons of water. This site on the issue suggests that 500 mg
should be more than enough ascorbic acid to remove chloramine
from the water over a period of several days. From site:

" SFPUC determined that 1000 mg of Vitamin C . . . remove chloramine
completely in a medium size bathtub without significantly depressing pH."

500 mg should be sufficient for our purposes. This makes dosing rather
easy as well, as a 500 mg tablet soaked overnight in a mason jar is quite
easy to dissolve and add to the reservoir.
