Don't worry about doing the conversion from mg/L to oz/gal yourself. Just let the mighty google do it:

There's an easy peasy way to calculate doses of anything - just remember (or realise) that 1 mg of anything dissolved in 1 litre of water is 1 mg/L
Once you suss that then everything just becomes simple arithmetic:-
1 gram in 1,000 litres = 1 mg/L
2 grams in 1,000litres = 2 mg/L and so on
Or for smaller volumes just divide down so, if you want, say, 20 mg/L in 100 litres just scale it this way:-
If 20 grams in 1,000 litres = 20 mg/L
2 grams in 100 litres also = 20 mg/L

As Manky has said ... 20g in your 1000L is 20mg/L = 20ppm.
I would leave it longer than 4 hours unless it's a really delicate plant.
Must be big for such a large container .... what is it? ...
Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
