So still in the planning stages for my new 220 litre tank whilst I'm waiting for it to be built. I have this fire extinguisher left over from my marine system (2kg see pic) and it's full so thinking of using it. What I don't know though is how long the bottle will last on my tank (I've not used co2 before on freshwater)? And if I'll be able to get it refilled? I seem to remember that when you get a refill they don't actually refill your bottle but instead swap it out for a full one they already have? What I'm worried about is how old this extinguisher is (I don't know and can't see anything on it) and if they'd accept this as a swap (assuming I'm right about how they refill it)?
Thanks
