That actually works sometimes, But in the first pic the swords and crypts took over, so did the Vals. In the 2nd pic, I just took some of the plants and moved them to my 55 gal., and even though the HC was growing so was the hair algae in the HC. So I pulled most of it up and I will try again.
This was before I started dosing EI ferts and had a good flow of CO2. Once I pulled the HC and algae up, I haven't see it again.
I just need to find a good deal on HC and I'll try again.
