I got my CO2 reg from CO2 Supermarket and got it all running. It took a bit of adjustment, but seems to be running OK.
The
Echinodorus tenellus that I got from Ryan all started to melt, so I had to sort the spray bars out quick
.
I bought a 2m length of PVC tube off a local company advertising on Ebay. They cut it in half for me and also cut some discs of clear pvc to stick on as end caps. Then, using a pillar drill, I drilled holes along the length of the tube. I used aquarium silicon to stick the end pieces on and let them set.
The distribution of CO2 is now much better; the
E. tenellus is picking up, and the
Hydrocotyle verticillata is too!
I've got a second length of tubing available to use on the RHS filter outlet. I'm not sure yet if I'll use it, or just continue with the existing short bar (just visible on the right in the picture above). I've deliberately fitted the CO2 bar a couple of inches down into the tank and tilted it downwards slightly. The shorter bar is aimed almost horizontally, and just moves the surface a bit. This has allowed my little ring paddock of floating
Pistia Sp to spin around quite pleasantly.
Through conversation and reading, I've learned that my hard water might be causing some melting. Does anybody have any suggestions on this? I've mixed up my Ei in 2.5L bottles, so could easily decant down to 500ml and add extra content if directed.
