Im on well water, which is great for chlorine but my kh is at least 250 ppm. Current ph 6.8, hoping this will lower a bit with pressurized.
I want to install this co2 system but am unsure if I can use any old needle valve like from home depot, or do I need a fancy aquarium type gizmo.
I welcome any input anyone may have for a beginner
I was using a Watts brand needle valve from Home Depot and it sorta worked but I could never get it to dial in and stay dialed in. I'd honestly not recommend it unless you really want to give it a try with the expectation that it may not work.
Maybe try checking for an Ideal Valve or Fabco dealer near you?
I agree; the needle valves that you can obtain from the local hardware store are not suited for our needs in the aquarium. They are unable to provide enough control to provide the low flow rate that we require.
