hey man,
sorry for the late reply...anyways yes, Red Sea makes a system that works with paintball bottles and regular tanks, but i would stay away from this.
just by looking at the regulator and parts i could tell its very cheap. also, the needles valves that come with this kit are sloppy and dont hold the flow rates well. some of the best co2 components are the ones that are pieced together and not made from some big aquarium name company.
so first question, do you want to run a ph controller or simply have your solenoid on a timer to turn on/off with your lights? i was first going to go with a ph controller, but after doing lots of research decided against it. many people claim that once you get a feel for planted tanks, the ph controller becomes more of a monitor. a simple drop checker for $10 is effective for finding out what your co2 levels are.
with that, Milwaukee makes a decent regulator and ph controller. both are available on ebay for about $190 shipped, or you can buy them individually. for the money, the regulator is decent. but i have read several complaints about crappy and sloppy needle valves and the low pressure guage going out. i then decided to ditch the ph controller, and use the money saved for a higher quality regulator. the regulator assembly is the heart of your system. go cheap here, and you will pay for it down the road. here's the full kit on ebay:

and here's just the regulator for about $90
Regulator
stay away from the kits that Dr. Foster & Smith sells. theyre junk and too expensive. they use cheap components and even give you the wrong kind of tubing (silicone).
now, if you decide to go high quality, you have lots of choices. off the top of my head, these are some of the better ones out there:
Rex Grigg's best regulator $141, base price
Green Leaf Aquarium $99~$210 (i bought the 'Choice' regulator. see my thread
HERE
Sumo Regulators $115~$2XX (claimed to be some of the best)
There are other companies that sell these types of regulators, but these are some of the more popular ones.
you cant go wrong with any of these really. they all pretty much use the same brand parts in the kits they assemble. Clippard, Cornelius, Fabco, etc, etc.
What really makes the price differences with these are the needle valves. good needle valves are VERY important as this is what is gonna control the flow of co2 into your tank. you want something that is easy to fine tune as well as something that is gonna hold the same flow rate and not go out of whack everytime your solenoid shuts the power on/off.
heres some of the better needle valves sorted by quality and price. clippard are the cheapest/lowest quality. of course, there are more options but these are some of the more popular ones youll see sold with kits:
- Clippard
- Fabco
- Swagelok
- Ideal
i hope this was helpful. let me know if you have any other questions. the main thing to remember here is that when it comes to regulators, you get what you pay for. it might be cheap now, but as i said, it will cost you more down the road.
good luck
