The pressure at the meter valve is irrelevant as long as it can handle the 1-10 bps we usually use in these reactors. I run 10 PSI on mine. Sounds like this guy is blowing smoke up your you-know-what with running 1000 gallon tanks on one, IMO.
The trick is to get the longest water dwell in the reactor without collecting excess CO2 in the top of the chamber, making noise and wasting CO2. This can be achieved with a ball valve on the output to choke back flow or a bypass if you run inline with your canister. I have played with the idea of making an accordion style box with baffles that require the water to change direction several times during it's route assuring that the gas has time and ample surface area to mix.

Jim got a pic of your sump set-up, was thinking of similar set-up for a big 180g tank. Will be breaking down my tank by the end of this month for our big move to our new house.

|Kathyy||How much water is going through your reactor? My 12"x2" reactor could handle 200gph and the 20" cerges can handle somewhat less than 500gph without too many bubbles escaping. Perhaps you could split the return to reduce the load on the reactor?|

My reactor is basically a 2" PVC pipe that has water going in on top and out on the bottom. My co2 goes into the pipe about 3" from the top. I was told this is the best way to breakup and dissolve the co2 into the water. Instead I get really big bubbles entering my tank.
I just have the single return in the middle of the tank and wasn't sure if I just had to much water pressure. I gave up on the bubble counter weeks ago since it is just a constant stream. But the DC barely ever changes color....more so a blue/green color.
Really starting to drive me crazy. I thought the sump set up with a filter sock would be the best way to go but not sure so far.

As for my plumbing; from the return pump in the sump, it goes to my reactor, from the reactor it goes into a Y, that then goes to each return. I am running MAG 18 (1800 GPH). I am using flex PVC for all my plumbing, also not using any 90's. All my plumbing is 1 inch. I don't have the MAG18 turned down at all so I am getting fair amount of turnover, also have my UV split from the MAG18, but that has a gatevalve to control flow. Assume you have PVC running from top to the bottom of your reactor? Inside of it?
As to help off gas of CO2, I have my sump covered with plexi glass, as for my overflows, I am running durso standpipe on each, and have some poret foam to help with the splash.
When you say it won't dissolve, do you mean your seeing the tiny & large bubbles in your tank, or that your drop checker won't turn green?
I had a problem with both at first, I filled my reactor up with a bunch of bio-balls real small ones, maybe half full with no water in it, and that helped with seeing large and most of the small bubbles in the tank.
If your drop checker won't turn green color, I had a lot of problems with that as well. It took a lot of adjustments to CO2, to get right balance. I cannot count the bubbles in my bubble counter. I have given up with that, and just adjust it to my drop checker is the right color.
Sorry this is so long, way more info than you wanted I am sure, but I figured I would give you full details of the setup.

Jim_PA do you just have one return going back into your tank from your sump? Mine is like that and I have a 900gph pump and for some reason can't get the co2 to dissolve in the water at all. I have a 20" Rex Griggs reactor and not sure if its to much water pressure.
I'm asking you cause you seem to be the only other one in here that has a planted tank with a sump.

|Jim_PA||Glad to hear it working well for you. Mine been working great as well. It needs a good cleaning though. I am thinking about doing that this weekend, not really looking forward to moving that monster from under my stand.|

|inkslinger||Will so far this set-up has been great at dissolving all my co2 100% and I am running less co2 at this time and it's keeping my Drop Checkers on both end of the 60x18x24 inch tank green every day. I'll say this is the best set-up I ever had.|

Will with this hot weather I'm thinking of removing my elbow with heater an go straight out to the tank, The tempt in the tank stays about 2* below room temp all the time. So far the system is working great , I get 100% diffusion in my 110g tank , just got to add some
little flow with power head.

Will I finely finish my reactor , I got too say this works great with my Eheim 2262 filter. I have a 3in x 1in suction screen on a 1in pvc then I added bio mini balls and fill it to the rim, It dissolves all my co2 and am able to run my bubble count way less than when I had the ext 5000 reactor , no bubbles being blown into my 110g tank and it's so quit.
The pic shows how big the reactor is to the ext 5000 and I use a 5/8in tee from aqua medic for my co2 and with the bleed valve on the filter makes filling with water a breeze so far a 10lb co2 tank last me 6 months with the ext 5000 reactor, I hope with this new set-up I can get at least another 2 months

|inkslinger||Will I finely set up my filter and only took 10min to replace the ext 5000 reactor that I had in the first place , with my Eheim 2262 filter pumping at 900gph it is so quite and my co2 at 3bps I drop from 8.7 to 7.3 in 2hr for a 110g tank. Well post pic's soon of my new set-up.|

I still haven set it up yet ! I got it all put to together , I've got the 1" ports and used
reducers to 5/8" Eheim hose . I like the size it's B I G!! I have a 36" high stand and I
can't mount it underneath . I'm going to use bungee cords or straps to secure it . The
Eheim 2262 filter will hold it up some the house filter sits just a tad higher from the pump.
The inside is like 5 1/2" round .
