Seachem Flourite Black.
I think solve the rooting problem, I'm getting some nice results now, same as before. I deep vac the top layer and got out a lot of mum and dead roots. I think it was too dirty so the HC Cuba was trying to grow in the water column.
The roots were fine, it was just the lower part that was in the substrate that die off, got a ton of growth on top which eventually floated up. Anyways, hopefully this new growth continues.
Oh and ADA 60 - P, in a month, yay!
