looks like you're probably going to get a nitro tank from airgas... https://www.amazon.com/Taprite-Gauge-Nitrogen-Regulator-Valve/dp/B0163E9SLI/ref=sr_1_2?dchild=1&keywords=nitrogen+regulator+taprite&qid=1589847884&sr=8-2 I would also recommend a regulator like this instead of the micro thing. get some solid hose clamps on all the lines and a tank should last several kegs.
