jaidexl, you are really stretching the limits of what can be expected from DIY Co2. you already have problems with your Tonina Belem, L.I.V.Cuba won't do well either without compressed Co2, and there are similar looking plants that will do fine without it.
Wow, I've been locked out of the site for over a month for some reason, finally kicked whatever did it.
Anyway, the pressurized bottle is in and pumping away as of monday, finally. Kind of wish I'd have seen your post before I bought a bunch of LV cuba from an APC'er yesterday, but what's done is done and hopefully I can meet it's needs. It will be in the new 65gl with pressurized co2, 192 watt pc, and laterite>eco>SMS charcoal. Still would like to here some good easy/moderate alternatives that you have in mind.
