What Should I Do With My Tank?

[big mick]

I have a 300ltr tank which currently houses 2 green severums 5-6" (which I rescued from a frinds 100ltr tank a few months ago), 3 bristlenose plecs 4-5" and 2 clown loach 5"

I was trying to decide if I should try breeding the severums as Im pretty sure they have been pairing off or remhome the female and get another tank mate for the severum (not sure what though)

But now Im thinking of rehoming them all (minus the clown loach) and getting a Co2 system and having a nice planted tank with more of a community tank.

What sort of price would a Co2 cost and what exactly is it (excuse my stupidity)

You will find everything you need to know about CO2 on the planted tank forum. With a 300l tank, you will be looking at a pressurised CO2 system. German ebay sellers appear to be the cheapest option for this.
