Ok, Iíve got an update regarding the tank!

The Ludwigia Palustris is mostly not doing good, only one stem seems to be growing well. Iíll wait until it emerses 1-2 inches and then try to cut and replant the top.

The cryptocorynes have not melted as I read they probably would, which I am very happy about.

The Limnophilla sessilflora is doing really good, so I bought another pot from the same store, which happened to be their last one. I planted along the length of the tank, hopefully in a few weeks it will form a green wall hiding the heater.

I added Salvinia Auriculata, in order to keep the water column from getting filled with NO2 and NO3. That store sent me some fully grown which is really impressive in such a small tank. Their roots are long and some are dark too. I wondered initially if that was natural, but I keep seeing it in good condition so Iíll leave them be.

Added two pieces of hardscape (a rock and a piece of wood my brother had) and two plants on them an anubia and a bucephalandra.

Last, I planted a carpet plant, marsilea crenata. Curious too see how she grows!

The only problem is that I still have mesasurable NO2. Last three measurements were 0,29, 0,31 and 0,69 mg/L. NO3 gave 32, 33, 45.

I am wondering if the daily big water changes are inhibiting the Nitrifying bacteria to develop. I have been doing >70% daily water changes to battle the algae which in conjunction with the floating plants worked. But I can still measure NO2 and NO3. The other parameters are fine. GH 10, 11, 11
KH 19, 18, >20
pH 7,9 8,1 8.
Cl2 0 0 0
CO2 8, 4, 6.
Temperature is constantly at 78-79F (to be exact, 26 Celsius)

Should I continue with such large daily water changes (50%)? Sounds intimidating if someone was to build a 100gal walstad tank...
