Thread: Co2 fill ups

  1. #11


    I used to pay around $32 to exchange my 10lb, this time i went to bacon equipment co in dallas and they fill it up on the spot, it was $32 for 2 10lb bottle. Theres a hydroponic store by cowboy stadium that'll exchange 20lb cylinder for $26 out the door.

    Someone can correct me on this if I am wrong.. but my understanding of turning off your CO2 with the lights is that your plants are not processing the C02 and it causes a buildup and a dip on the PH level.

    The buildup of CO2 will cause the PH to drop, lights out will exacerbate the situation. At what rate/intensity varies substantially so it could be a non-issue or an actual issue.

    Bigger overarching reason is to not waste CO2 on plants that aren't gonna use it. It's universally true.

    I've used beer stores and do an exchange no problems. I use keg and barrels at 15 and custer plano tx and spec's just north of parker and 75 in plano. 15-20 bucks to fill up a 10 pound bottle.

    I know this is old but, I'm adding to the efficacy of the search function.

    You can fill co2 tanks at academy. Also, yes. Running co2 at night will cause a ph dip due to the plants not photosynthesizing and the excess co2 acidifying the water.

    Academy does CO2 refills for paintball.

    just talked to Academy--sadly they do not do 5lb or larger refills or exchanges....

    I talked to GatSplat indoor paintball which has locations in Keller, Lewisville, and Rowlett--they will do refills and exchanges for 5lbs and higher... the lady didn't really seem to know their prices...said my 5lb cylinder refill would be $5-$7... lady on the phone wasn't sure about Keller's stock, but said Lewisville definitely had them in stock...the only drawback is their hours... i'll update when I try to go out there Saturday...

    Still looking for an affordable refill in the HEB area :-(
