So 2 weeks on, I'm even more confused than what I was before. I've not noticed any growth really other than some new roots form the Blyxa. That said, the Blyxa is shedding leafs but not melting at the stem. My CO2 level is such that fish gasp at the surface and I've had a casualty which was probably caused by this. My flow is better than ever with clear movement on all my plants, some even too much and they are leaving over in the flow. My Micranthemum Monte Carlo is just sitting there and doesn't seem to be spreading but it certainly is dying off as its remaining vibrant green.
My lighting is currently at 33%. I am considering upping this some more to around 40% to see if it triggers growth.
Would the collective recommend this? Or is there something else causing my lack of growth?
