Ahh rightoh no my sister added to much ammonia lol

Turn it off and give at least one side of the filter's pads (both the sponge and carbon) a good rinse in removed water, you might be shocked at how much more powerful the filter will be afterwards!

Not if he is doing a fishless cycle. Dont touch the filter at all it wont need cleaning. Turn it off for your WC's though.
