OBSERVATIONS OF TANKS

The observations made in the practical of all the tanks in the lab ad the following results:

OBSERVATIONS OF ALL TANKS

A	6.8	0	25	6	6
B	6.4	1	100	0	6
C	7.2	0	250	6	10

Best tank: C
Worst tank: A

The results of group three were not recorded due to their inaccuracy.

Visual observations in each tank

TANK A

• Temperature: 28 degrees
• There is an air pump
• There are different plant species
• The water is clear
• There is a UV light
• There is a mechanical filter
• the surface is clear of floating medium

 TANK B

• Temperature: 25 degrees
• There is an air pump
• There is algae growth on the rocks and leaves in the tank
• There is an LED light
• Mechanical filtration (Box filter)
• There is floatimg algae and also floating plants resembling lily pads.
• There is clear vegetation in the tank
• There are a few snails.

TANK C

• Temperature: 28 degrees
• There is abundant plant life, even floating
• There is a lot of algae in the tank
• There are many snails
