Στην σελιδα http://www.geocities.com/Heartland/H...637/index.html

λεει σε μια σελιδα εδω τα εξης τα οποια μαλλον καταριπτουν εναν "urban myth" σχετικα με το μειγμα.

Occasionally you will read on the web or in the newsgroups that you shouldn't shake the bottle to mix the yeast with the water. This is a classic net.non-sense which started with a post in the rec.aquaria newsgroup a few years ago. One guy posted the instructions for a yeast-CO2 set up, and wrote, "Add the yeast to the water, but do not stir or shake the bottle. The instructions from my bread machine explicitly stated this." What he failed to understand was WHY his bread machine instruction was so. Anyone with a bread making machine could see this specific instruction, under the "Delayed Baking" mode. That's the mode where you put the ingredients into the machine, then set the timer and go to bed. Near morning, the machine will automatically turn on and start mixing, kneading and baking, and you will have fresh, hot bread as you get up in the morning. The instruction tells you to put in the water first, then gently put flour on top of the water, then put the yeast on the flour, an DO NOT MIX. That's because they don't want the yeast to get wet and get activated too early, resulting in bread that rises too much.
Anyway, this guy did not understand the reason for that instruction, but passed it on anyway. People read this guy's tip and started passing that piece of non-sense around. It made its way into archives, and occasionally pops up here and there. I always have a good laugh when I see it.

Since we want our sugar solution to start fermenting as soon as possible, please by all means, mix the yeast well. But don't shake the bottle after the cap with the CO2 hose has been screwed on. This might get some of the liquid into the line, which will be pushed into your aquarium once the CO2 starts producing.
