C02 regulator

[250mixreef]

Can someone recommend a better regulator than reef fanatic. Seems like I'm using more co2 than normal. I've checked it for leaks and can't find any. I often have to open it up and lubricate the Piston which is a annoying . I'm on my second one and it looks like I need another. I'm getting about 2 yrs out of them. Is this normal?

Don't know the brand you have but the ones from aquarium.com regulators are known to be one of the best.
I had two on my systems and still have one on the DT, 5 years now and still super accurate.
