hmm...i luv your project idea! you could also try adding sodium bicarb to the water so tht all your plants and fish get carbn dioxide in sufficient amounts. be sure to place it in sunlight to allow photosynthesis. be sure to put in marine plants in the water so that the fish get oxygen to respire.

all the best!

The Newtons and friends were taking tea
Beneath the boughs of an apple tree,
When a falling fruit landed on the
Head of the head of the family.
Mrs. Newton cried, 'Well deary me!
That could've caused an injury'.
But clever Isaac alone could see,
The situation's true gravity.
