Planted Aquarium Project - Regulator for Fire Extinguisher

Hi,

I've picked up a couple of fire extinguishers for a planted aquarium project from Homer and need some advice on a regulator.

Really appreciate any insights or recommendations and especially any experiences with purchasing a regulator from ebay.

Thanks

All i can tell you is that after trying two regulators i finnally chose one that has a needle valve to regulate the flow and it works great , a bit more expensive but well worth the extra money.
