I had no idea that rockwool would add phosphate to the water. I am glad that
you mentioned this, there are times when I get plants and just stick the
little pot rockwool and all in the substrate. In fact I have a couple in the
tank now. This could be a contributing factor to my small alage outbreak.
Thanks for bring this to my (our) attention.
