Initial set up can be. Check on eBay or Amazon for the price of a small cyclinder (2.6kg or 5lb) and an aquatek regulator, co2
tubing, diffuser (inline is best if u use canister filters) a co2
drop checker and a bubble counter.
I suggest doing abit of research on co2
if going down this route. U MUST maintain 25-30 ppm
for the duration of your lighting period.
Tank refills are cheap and a tank will last u about 4-5 months
