So I'm between a few regulators. My preference would be to buy one on amazon if possible since I have some gift cards to use up there.

The only one I found on amazon that wasn't super pricey is this one: http://amzn.com/B003GMBT7M

But it would need the CGA 320 connector I know my tank has.

This regulator seems like a good deal on a name brand brass unit: http://r.ebay.com/2YEzvH

This guy seems like stainless and possibly nicer, would love an opinion:

This brand wasn't mentioned in the article so I'm unsure.

Another AGA:

I think it is worth it to try and get a regulator with a CGA 320 connection already on it, as that connection will cost around $20 from my adminittedly short shopping.

I also am going to be needed a ph controller. I don't think I want a full reef controller, so how I would I hook up this guy: http://r.ebay.com/lqfO4d to a Milwaukee MC122 or similar.

I already found that hoke 1300 series metering valve listed on Ebay that was given here, that should be here in a few days.

All in cost for all of this will be $313 assuming $100 dollars for the regulator. Should I just buy the fittings (like elbows etc) at a local welding supply shop? I live in Houston so I'm sure there are a few around.

BTW I really liked the article, it was what pushed me away from investing in a dosing system and deciding to build my own reactor from various used bits.
