    So, now I've got my regulator stuff all set. Hooray! ..wait, I need Co2.. :rolleyes: I need to work on my forward planning.

    55 gallon, reasonably planted, 2 wpg T-5 HO. I've only got 23 inches from bottom of the stand to the top, so a 20 lb and 15 lb tank are looking like their out of the question due to height restraints. How long can I reasonably expect a 10 lb bottle to last?

    Bummer. My 20# cylinders are 26½" and 28" tall.

    I don't have a 10#. I guessing, maybe it will last 3 to 9 months depending on rate. ????

    I wish I had space to fit a 20lb.

    3-9 months would be about the range of most tanks. At 2wpg T5HO I suspect you'd be on the lower half of that range by time you find non-limiting CO2.

    Thanks guys. I do intend on cutting out one of the bulbs to begin with, but I'm guaging the extremes in the case that I get froggy..which I expect to happen sooner or later.

    I'm running 2x54w T5HO (geissman, 6000k) over a 48 (sold as an oceanic 50 gal) right now. I've been finding running each of the bulbs for half the day with a couple one hour bursts works well.

    A Year

    Hi,

    People never accept this; it is true never the less, less light in the beginning increasing with biomass. :)

    With less light in the beginning starting very low on the CO2, work your way up slowly, if you choose dissolving the CO2 rather than watching the bubbles a 20lb bottle should last a year, perhaps longer. :cool: You could run a line upstairs, talk to Left C.

    Everyone do as you wish, I do not wish to argue. :cool: See disclaimer. :eek:

    I can't cut mine in half like that. GLO is all or none, not even an on/off switch. I'm basically just stuck with unscrewing the bulb until my tank gets worked up to the two.

    I take more of your advice than I think you give me credit for. ;) You think I came up with the potting ozelots in osmocote plus myself (among the many other things)?

    Left C spoke to me about running a second line upstairs a while back. It's improbable/impossible for me, though, as I also house an overly inquisitive animal of the toddler species.

    You Are Kind

    Hi,

    Thank-you you are very kind. :)


    Others read this forum and while I wish to give you and anyone else I write to my best and always honest advice and opinions, I have learned that I need to be clear and understand that some of this stuff, for whatever reasons is simply inflammatory.

    I have dealt those little critters of the toddler type myself, that is why God created drills, wall fishing wires and plaster. Uh, not for the kid…:eek: to run the tubing upstairs… :D

    Use copper pipe instead of tubing to connect your two tanks. Then use tubing near the tanks where you need it. ????

    Reinforced Tubing

    Hi,

    I was thinking more along the lines of reinforced braided tubing. Something like this http://www.kegkits.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=3230-41003-100&Category_Code=HOSE&Store_Code=W.

    The problem with most tubing over six or eight feet is that it incurs pressure losses.

    Most rigid CO2 delivery tubing is Aluminum, stainless steel or PVC. I know I have seen rigid Aluminum and stainless steel with Swaged ends. Rigid tubing is a lot tougher install.

    Something like those materials would be a much better solution than copper.
