I use 2*18 W over a 90 L (~23G) measuring 100*30*30 cm

No bright pink inner leaves, the rose is shaded by a C. cornuta, but grows very well producing almost bronze coloured leaves

Slight surface agitation just over the outlet, but the tetra bells aren´t completely empty
when I fill up next morning ( and I do blow out eventual residual other gasses when filling) making me guess the water takes what it needs )

Follow your suggestion, took out the o. No corm, but the roots were all rotten. ( wonder what caused this)
Cleaned it until only the rizome and 2-3 small white roots were left together with
2 small leaves. Replantet in the other end of tank..
Time will show
