Micro algae -> Zooplankton
Need to construct 2 parts, plankton light reactor (for micro algae) and plankton reactor (for zooplankton). Zooplankton feeds on micro algae. Both reactor are same design, just different in lighting. Micro algae need 16 max 16 hours of light.

Fish 2
What are the things need to checked and maintained in an aquarium?
1) PH level
2) Temperature
3) Ammonium level
4) Nitrite level
Nitrate level can also be monitored, but it is not so critical as above. A partial water change (20 - 25% of water volume) weekly can bring the nitrate level to acceptable one.

How to format Acer notebook
If you have the recovery/system CD
1) DELETE all partition exist in the current partition.
2) Use System CD, boot from it.
3) Follow instruction (GHOST program will come out, you need to have all Recovery CD).
You MUST delete the existing partition because Ghost can only recognise FAT32, if there is NTFS partition, it will not work.
