One gauge is reading 900 psi, the other one 30 psi....how should I read this??If you are happy with a mist then could probably ditch the diffuser & just feed straight into the external pump.
You could of used a needle wheel pump & that would of bee a totally maintenance free & reliable method of getting a mist.
However most guys get fed up of the mist eventually anyway.
The type of diffuser you are using can cause a few issues but with a bit of luck you should get it going... what is your working pressure at the moment?
I know mate - it's my favourite plant, and there is a "mini" cultivar I've seen with much smaller leaves which looks as though it grows quite dense, with just the occasional leaves heading for the surface... I could also move it out a bit more into the mid-foreground...Might have to keep the zenkeri trimmed to keep its leaves close to the substrate mate or it will head strate for the surface.

£30 psi is about 2 bar off the top of my head, possibly not enough, the more standard UP requires more like 3 bar to work well!One gauge is reading 900 psi, the other one 30 psi....how should I read this??
Just realised that a needle wheel impellor in my circulation pump, with CO2 supplied via a venturi would have been a much simpler solution !! Might try and retro-fit this....
Hmmm...the pump I'm using is a V2 Powerpump - rated 2000 LPH - must say I've had to restrict it slightly, but it's good and quiet. Just been looking at Alastair's home-make pipe reactor (see above) and think this will work better - also won't need much working pressure....new territory for me, but will integrate into my plumbing arrangement really easily.£30 psi is about 2 bar off the top of my head, possibly not enough, the more standard UP requires more like 3 bar to work well!
I ran NW pumps for many years, including some really big tanks, once set up they require no adjustment for years...
Tom Barr also uses NWs for many of his tanks.
Yes, been thinking about this too...trying to get some surface movement, but have some flow at the base as well - have gone through about 3 meters of acrylic pipe today, trying various designs...and still not there - still got work to do on this....If you consider that in your set up, the inlet is at the bottom of the tank, that is were you want your gas to get too!
Rather than direct it up perhaps direct at a low level.
I could imaging a rotating head about one third up would really do the job but might not look to good?
Thanks very much. Yes, have thought about putting the diffuser before the filter....would be reasonably simple to do, but always worried about unseen build-up of CO2 inside the filter - I assume you've don't have this issue?
After all that, I'm actually going to take the diffuser off completely and try using a reactor insteadNo, no, never had this issue. Although my diffuser is after my filter
I have been using a Mixmax Co2 reactor which has worked fine for me and keeps the bubbles very small, my outlet is also just above the gravel at one corner blowing a fair current across the plants, if you watch a bubble it seems to dissolve before reaching the surface.
Alistair's reactor thread is a great guide, personally I would try your hardest to obtain clear tube & understand the longer the bubble contact time the more efficient the reactor... in other words you need a long tube!
As you appear to be pretty handy, you might want to attempt to get the water inside the tube to spin as this will obviously increase contact time tenfold.
Yes I know - very strange. It leaked where I'd put in a reducing bush to come down from 2" to 1.5", and I did not they were quite lose, so I guess I should have used more glueLooks the business now its inside the cabinet. Very well done mate. Shame about the leak though. Pvc cement usually bonds in minutes and should have been a tight seal after ten. Unusual
