Ok (although it's no bother if it removes nitrates unless you
specifically want them left in to fertilise plants).

You can buy another blue sponge from a fish store for a few
quid if you prefer - you'll want spares in due course anyway,
right? Might want to stock up on filter floss (or white sponges
if you prefer, but floss is far cheaper and you can cut it up
yourself) anyway.

Tomorrow I will be building a diy CO2 kit with check valve. What is your
opinion on these?

I'm sorry, I've never tried one so can't help - try asking in
a plants newsgroup? Guess the guys there have more experience
of CO2 systems.

Best of luck!
