Danny,

you could add a sponge filter to the air supply if you feel the current filtration is inadequate.

Did your teacher have any particular reason for removing the top? I don't see the purpose in doing something like that... Africans are very tuff and can handle a short power outage. However, if removing the top is all he did, i doubt the extra light is what killed the fish... what else was done for hurricane prep

I'll PM you my e-mail, feel free to contact me directly if you have questions or pass on my e-mail to Mr. Wallac if he would like to contact me.
