Just use it if you want instead of a blue. No issue.
Your sponges are just things which mechanically filter big
lumps out of the water, and which home bacteria which naturally
take harmful nitrites and ammonia out of the water. As long as
what you use is inert and vaguelly appropriate, you could use
other stuff. For example cannister filters use a mix of sponges,
ceramic rings, filter floss, carbon granules... so it's not a
big issue!


the only problem is i am cycling the tank, i don't want that green sponge to
kill my nitrites and nitrates straight away.
Tomorrow I will be building a diy CO2 kit with check valve. What is your
opinion on these?
