Slowly but surely.
With the main tank
I have not grown anything successfully where the water flows fastest, and just ended up sticking a bunch of trims and hope something grows.
Right side with Java moss, Crypt walkerii (?), and Hydrocotyle sp.
The Java moss is growing up the sides without training it.
My only successful crypt. I do not know what it is.
C. wendtii.
H. leucocephala
P. palustris aka "Mermaid weed"
Older pics of L. repens "Rubin"
The structure kind of acts like a wet/dry, and so is very messy with plant matter from the main. I did not intentionally plant M. tenerum here and have not spread it around. Now everywhere there's a water fall, there's M. tenerum. The red plant is L. repens "Rubin"
Didn't plant the M. umbrosum here either. I think it came from the mass of plants I dumped "upstream" a month or so ago.
I thought I got rid of all my Riccia over six months ago and never put it in the paludarium section. Didn't notice this until today.
I think this is R. rotundifolia
So I am not having much success but have hope. I am now spraying once a week with a weak solution of KNO3 and KH2PO4. The water column is ~10ppm NO3, ~3ppm PO4, >40ppm K, 2mL TMG 3*week, 4 dkH, 6.4 pH, >40ppm CO2, 50% water change weekly. Suggestions appreciated.
