Best grain for pale lager

Here's a pic of the lager I have been complaining about all day. All in all its not too bad just could be better.

According to Chris White and Jamil Zainasheff in their "Yeast" book, an aquarium pump will not give you more than 8 ppm of O2 and extended aeration can be detrimental to head formation and retention. With pitching rates required for lager fermentations you want to have at least 12 ppm of 02. The only way to achieve this is by using bottled O2. 20L of wort oxygenated with bottled O2 through a stone for 60 seconds will give you just under 10 ppm, while 120 seconds of pure O2 will give you about 14 ppm.

Cheers 4 the info mate. I'll have 2 sus out the local BOC gas agent for a bottle of O2.
