I can't seem to figure out what is going on with my AR Cardinalis . . .
Tank is about 2.5 months old.
Tank: Spec V
Substrate: FloraMax and some small gravel
Hardscape: Spiderwood and dragon stone
Light: 16" Finnex Stingray (8hrs)
Ferts: 1 pump of thrive 2x a week, a few Osmocote+ balls around the base of the AR and Bacopa, double dose excel most days
Flora: H. Diformis, JV Needle, JV Wendelov, C. Helferi, S. Subulata, Bacopa caroliniana, A. nana petite, mini christmas moss
Fauna: nerite (1), Ember Tetra (9), RCS (4 adult ~30 juvenile)
nitrate: < 20
GH: ~60 mg/l
KH: ~80 mg/l
Growth for almost everything except for the AR and SS seems good. I was under the impression that moss was slow growing but my mini christmas moss has exploded. B. Caroliniana is doing well and almost getting a pink tint to the upper leaves. Both types of java fern are continually producing new leaves and rhizome side shoots.
But then there's the AR . . . new leaves seem to be OK, but the older leaves are developing pinholes and I can't get rid of the algae on the surface of them. (there's no other real algae to speak of beyond a very light dusting on the glass that I easily wipe off weekly) I've read some other threads here that indicated that the holes could be potassium deficiency so I started adding enough flourish potassium to theoretically raise the level in the tank by 1~2 ppm 2x a week with my Thrive addition. I have trimmed off some of the worst ones but I'm worried it's just going to get bald underneath if I keep going. I've also read that these don't like to get moved, but at this point I wonder if I wouldn't be better off pulling them up and replanting the tops . . .
Am I missing something? Any guidance is appreciated.
