Plants in rockwool

Hey Henry, I don't know regarding the rockwool but regular flourite is a pain to clean. It is very dusty and does have a tendency to cloud the water when vacuuming. On the other hand Flourite Black sand isn't cloudy at all. I didn't even rinse the gravel and it barely had any impact on the water clarity when I filled my tank up. I think Flourite black is also similar in that it isn't very dusty.

 

Henry,

I usually remove as much of the rock wool as possible.

While I have buried plants with this still attached, I have not found it to be any more beneficial IME.

If you do leave it in, don't do it for long and remember to dig it out....Not sure if entirely degrades, but I have found pieces months later.........

Yes, normal Flourite is very dirty. I had the red in my 180 for +3 yrs and it was always dusty......

I switched to the black flourite and is much better.............rinsed easily at first and have no issues with replanting/scaping.

Hope this helps.
