Well the diatoms are now back on the plants - not hardscape or glass. The went completely when I dropped EI and went back to ADA only, but now the staurogyne is brown again. The lower stems have gone dark again, and anything below the top node of HC looks dark green and crap. It's also very leggy. Shouldn't be any problems with CO2 or distribution. I'm ready to rip it out. Anything I read about diatoms says they will rub off, but this won't. It's like the leaf itself is brown and it's been there for months. The only thing doing well is the moss now.
I was going to finish the scape after this last trimming of the stems, but some have grown fast, some slow, and some not at all so it's a right mess. Some leaves are big, some small.
