Hi all, have a big bag full of dwarf sag to give away - prob enough to carpet a 2 x 2 foot area. These are now out of my tank and sitting in a Ziploc bag, so will start to die before too long. Just sold my tank (boo) and the buyer didn't want the plants. Disclaimer - there may be snails and algae in there. Pick up from te atatu peninsula, let me know if you want them. Best to get me via text, 0210528720. Jay

OK, location added... Thanks for that Trademe link - those extinguishers look like a bargain! Having said that, done a bit of research into fitting regulators onto CO2 extinguishers and have come across quite a few warnings about the dangers of this, since extinguishers werent specifically designed to be fitted with a regulator. I'm sure 99% of the time it would be fine, but for my piece of mind I think I'll fork out for a standard CO2 bottle.

Thanks for all the replies! Really helpful. I'm intrigued about using a CO2 fire extinguisher for the bottle – what do you need to do to it to make sure the regulator fits into it? Would rather avoid paying ~$300 for a bottle so maybe this is a cheaper alternative... And Godly3vil would you be interested in potentially selling one of your old ones?

Hi planted tankers, Im thinking about moving from DIY to pressurised CO2 and just wanting to know roughly what the running costs are in terms of (1) refilling bottles and (2) safety testing of bottles (all Trademe listed bottles mention their safety test date so I'm assuming this has to be done every so often??). On my DIY I aim for 1 bubble per 2 seconds so would be using CO2 at about this rate. Its for a 36 inch tank. I'm thinking I'd try and use a 2-3kg bottle since I don't want anything too big... altho if anyone has any comments on whethe this size is appropriate would be great to hear. So my specific questions are: 1. Roughly whats the refill cost for a bottle like this? 2. How long will it last? (I know the answer to this will be 'it depends' but a ballpark figure would be great) 3. Do I need to get it safety checked, how often, and whats the cost? 4. and while I'm at it - is trademe the best place to pick up a bottle or can I get them elsewhere cheaper? Thanks heaps for the advice guys, appreciate it Jay
