JBL Proflora

[Nicki Gaga]

I am getting a pressurised CO2 for my soon-to-be planted tank and am looking for the right pressurised CO2 system. What I am so confused about is what is the difference between the JBL Proflora m502 and JBL Proflora m602? They both use the same m500 cylinder and supply the same tank volume. The only difference is the 'special hose' for the m602 is shorter than the hose for the m502. If anyone knows what the main difference between the m500 and the m600 series is, please let me know. With much appreciation.

I'm only looking for JBL CO2 systems as my local fosh store only refills JBL.
