Co2 For A 450 Litre Tank?

[adamgreen240]

Hello everyone, im currently planning a 450 litre discus tank with about 6-8 discus , 2 angels and a shoal of cardinals.

I wanted to have the tank planted quite heavily and so was wanting some advice on CO2.

Am i right in thinking it would have to be pressurized?? If someone could reccomend me a kit, that would be great. Thanks, Adam

Definatley pressurized. Most kits you buy contain 500g-1kg cylinders which are going to be pointless. My advice would be to use a fire extinghuisher (see 2 guides in sig) then use a 2kg FE, or even a 5kg which might be better.

I've got a 400 litre tank and I'm using two JBL 'Easy 2' kits - one at each end.
