what is the best tank to buy???

 

[Reef55]

all depends how often you want to swap it out, and how much room you have for it.

If your looking for a tank you need to post your location, I have a 20 lb, with regulator (Cape Cod).

And how many tanks/CA reactors you will feed from the tank

i have a 20lb cory and i haven't filled it in forever if you have room i'd go for a bigger one.

 

[nitrofish]

go with a medium one, they last so long anyway

I have a 5lb on my 90g, at a rate of 1 bubble every 2 sec's and it took 8 months to empty......

 

[maxfischer]

do they fill the tanks or just exchange them?? I kinda remember a post saying they only do exchanges on tanks. If that the case i have a friend that own a bar and will just get a coke one!

 

[Troubleman]

Depends where you go, nb welding supply will do either. i bought aluminum one in excellent shape and will only swap for equivilant......same price either way.

make sure it dosent say coke on it, they wont refill those unless you go directly to coca cola .
