Yep they connect to standard air hose sized tubing.
These are not super high quality (as you can see by the price)
Only a fraction of a turn is the difference between 1 and 2 B.P.S but when set the B.P.S stays stable and does not need readjusting
Some connect to the tubing like this one http://cgi.ebay.com/CO2-Needle-Valve-Re ... 3a4db1dcc7
I bought a 3 way splitter, each with its own needle valve. It connects to the regulator.

Nope. Just make sure that the floor joists are running from the wall that you want to use and not parallel to it. Its the floor joists that spread the load.
You have seen my 8 footer in my second story lounge.
Last Tasman club meeting there was 10-12 people standing in front of it adding another ton of weight to the same floor supports.
Need i say more
It sounds like the diaphragms are perished.
These pumps can be easily taken apart. they have 2 flat circular diaphragms.
You can get cheap diaphragm rubber from Para rubber
Sorry but I didn't have time today.
Next Sunday the Tasman club are doing a tank crawl around Nelson.
We are meeting at 9.30am at the Dick Smith carkpark in Richmond.
We could all come see your tanks if you are keen.
Pm me if you you are interested
LOL. I saw those in Pets 'n' All today.
I had a bit of a laugh then moved on to the next tank that was labeled as "Small Spotted Loach" only to find a Hillstream loach of some description.
At least they labeled to Banjo catfish correctly
