I wasn't sure where to put this... It's my 10 gallon brackish planted...
The algae is essentially dark brown spots around the middle of the front glass pane. The only reason it's bugging my is that it won't scrape off.
I tried a razorblade on the glass, and I was having so much trouble I ended up scratching the glass... And not even putting a dent in the algae.
The tank is planted with crypts (wendtii, blassii), swords (rosette sword, Echinodorus Angustifolia var Vesuvious), and dwarf hairgrass.
I'm up to 3tsp per gallon, added slowly, but I don't have a hydrometer, so I'm unsure on the exact salinity.
Any ideas on the algae, or should I just move everything over to a new tank? (I hope not.)
