Hi everyone i'm new to Virtual Viller and i have to admit i'm hooked now, but i have read that over fishing courses algue to appear, i have done a test game which the algue did apear and i know how to remove it etc but my question is how long does it take for the algue to appear.

1) After buying next tech level in food
2) buying a tech level in anything
3) after you have courght so many fish
4) its random

I'm now saving up all my tech points and not buying anything like i did in the test game, so i can build up the food points in the hope that i can get over 1000 points before the algue appears, at the moment i have 500 food points and i haven't tried to increase the village size since i need to have as little food eaten as possible because i'm new and want to learn rather than rush through the game.

Also would you recomend while sleeping to put the game on either pause or slowest speed?

Thanks in advance
Roy.
