Changed the co2 from yeast/sugar to a citric acid/bicarb mix as an experiment. Running 1 bubble per 1.5 seconds roughly.
I made a DIY clip for the heater, as its too long to be able to clip to the bowl. I need to redo the clip as the glue didn't hold the pieces and I've had to use a cable tie to joint them as a temp fix, so it doesn't sit so squarely. I have the BiOrb heater clip, but needs a much shorter heater, and I don't want to shell out £30 for BiOrb's heater kit. So I've made it so it clips to the heater firmly, and to the uplift pipe much less firmly, so no risk of accidentally wrenching out the pipe if I have to remove the heater! Temp is 22deg. Without the heater, temp was settled at 16.
Plants I stuck on barbecue lava rock (mobile plants if you like):
Hydrocotyle is growing well and will probably need some cutting back.
Spiky moss has now pretty much fully covered it's barbecue lava rock!
Ludwigia seems to be picking some colour back up as it gets higher, looks to have a slight hint of browny red coming on.
Polysperma doesn't seem to be doing much except gaining algae on leaves :/
ED is slowly gaining some strength but not yet running amok. As its behind the filter uplift, im hoping that as it gets higher, it'll pick up some current and swirl around the bowl.
Cypt crisp appears to be not dying. Also not growing, but it seemed to wilt a little and has picked up a bit since...
Dwarf sag has done nothing. Well it's leaf grew a bit taller, but aside that, it's been lazy. I've cut the leaf in an attempt to encourage its growth.
Still a lot of unused space, perhaps I need to remove the hydroctotyl rock and plant it into the substrate?
