aquariumplants.com Co2 Regulator
 

Is anyone using this regulator. Any opinions, I am looking to replace my milwaukee with something that is of a little more quality.

Looks very similar to the one I purchased from J&L - http://www.jlaquatics.com/phpstore/s...ct_ID=cr-pprnv

Used it for years with no problems.

I've heard of it being recommended on other sites. I'd like to replace my Milwaukee as well... Aquamedic also makes a regulator which I'm considering as I've had very good experiances with all of their other products.

I use the Aquamedic regulator, solenoid and controller, I've had great luck with their stuff as well.
If your looking for a needle valve the Red Sea is working great for me and I thought the price was pretty reasonable.

Well I got the aquariumplants.com unit a couple days ago. So far its rock solid. I have to say the gauges are the best part. The scale on them is so much better than compared to my millwaukee. The low gauge tops out at 15psi, this makes for easy tuning.
