Hi all, can you help me figure out what deficiency these swords have? I have fluval 3.0 lights running 9 hours at 90% intensity. No co2 injection (Yet). Fluval 407 filter, no phosphate pads, recently added fluval nitrite pads. I use root tabs, dose flourish potassium and phosphate (bieeekly) and iron (weekly). I also have a diatom problem that I cannot seem to fix. Tank is 55 gal and established. I do weekly water changes about 30%. Phosphate tests 0, nitrates around 10-20 right before wAter change. No ammonia or nitrites. I have 8 cardinals, 7 Odessa barbs, 3 pearl gouramis, 2 balloon molies, 4 juli corys and 4 green corys (tank is slightly overstocked). The plants are not new but I cannot seem to get them to look like the pictures I see online. New growth happens but leAves deteriorate as they grow. I will start injecting co2 soon. I have some Java ferns that do not seem to thrive either. Any help would be much appreciated.
