Flourite Black Substrate.
Since Flourite has a high CEC (holds nutrients), I thought it be pretty good to have a lot of mulm. Is there a time when there is too much? Beside the fact that it is ugly near the glass, I'm having a hard time getting my plants to root.
Tank is nearly 2 years old, never deep vacuumed, never really touched the substrate at all. All my fish are nearly 2 years old, my 3 Otos are past half a year old so I'm guessing the parameter is fine.
So, could too much mulm cause plants not too root? They grow great out of the substrate but any plants such as dwarf hair grass is stunned to the point where I just take them out.
Here is the HC Cuba that I had to pull out, it just won't "root" anymore. I had it pretty good once.
I trim, I trim and I trim some more, it is not a trimming problem. The area is exposed to light, the Cuba just grows only on the top. It's like all of sudden it decided that it likes to grow floating.
