Fluctuating CO2 levels

• pH: 6.8-6.9
• Temp:
• KH: 5
• GH:
• NH4:
• NO2:
• NO3: 0 before dose
• PO4: 0.5 before dose
• Iron:
• Dosing: 15 ppm NO3, 1.4 ppm PO4, 2 tsp CaCl2, 0.5 tsp epsom salts
• NO3:PO4 Cumulative Dosing Ratio: 15:1.9 = 7.9

Notes:
50% water change:
25 mL Amquel+
2 tsp CaCl2
0.5 tsp Epsom salts
2.5 tsp baking soda

The last extra dose of CaCl2 a couple days ago seemed to help the plant growth a bit. For this week, I did not add any Equilibrium, just Ca and Mg, meaning no K.

The BGA seemes to have gone away, probably due to the nitrate dosing. Other algae, including staghorn and what disturbingly looks BBA have been growing in more. The CO2 levels might be fluctuating, because the CO2 levels haven't been as high as expected even when I noticed that the CO2 bubble rate had creeped up. For whatever reason, I haven't been able to keep the Co2 flow rate steady. I'm going to keep a closer eye on the CO2 this week.

The leaves of the new Kleiner Bar plantlet are starting to grow in nicely.

This is a picture of the tank after week two of letting the green dust algae remain on the tank walls. The green dust doesn't seem to be increasing any more, and some spots have even been clearing up, probably due to the otos or SAEs eating away at it.
