Hi All,

2020-09-07
Yesterday was water change day. I did a 50% water change and took the opportunity to make some of the plant species changes I mentioned earlier. I removed the sad Persicaria sp. 'Kawagoeanum' which had very little root system and they went into the compost pile. I removed all but one of the Limnophila rugosa which had good root systems but poor growth and I moved them to my 75 gallon. The Ludwigia sp 'Red' (which to me doesn't look like L. sp 'Red') was cut down to remove the emersed growth at the bottom and replanted just the submerged growth tops; the stems all had a good root systems. I dug around in my tanks and plant bank and added a couple of Nymphoides hydrophylla (aka sp. 'Taiwan'), some Rotala H'ra (aka 'Vietnam'), and a couple of stems of Limnophila sp. 'Wavy'. Here a picture showing the new layout and trial species.



1) Nymphoides hydrophylla (aka sp 'Taiwan') hiding behind the 'Trident'
2) Rotala H'ra (aka 'Vietnam')
3) Limnophila sp. 'Wavy'

Here are a better shots of the three species I added. First Nymphoides hydrophylla


Next Rotala H'ra


Lastly Limnophila sp. 'Wavy'


I also took a full set of water parameter readings after the water change and plant changes; here are the results:
pH = 6.8
dKH = 2.0
dGH = 4.0
Ca = 20 ppm
Mg = 5.23 ppm
NH3 = 0.25 ppm (possibly from disturbing the substrate?)
NO2 = 0.00 ppm
NO3 = 10.0 ppm

The fish are eating three meals a day consisting of frozen bloodworms, frozen adult brine shrimp, frozen adult brine shrimp with spirulina algae, freeze-dried tubifex worms. The discus are not really interested in Fluval Bug Bites, Extreme Krill Flakes, or Extreme Pellets. My live white worm culture has grown large enough that I should be able to add that sparingly to the food rotation.

Have a great week everyone! -Roy
