I've read many articles about Staghorn algae and people usually say it's because of some high ammonia spike. I cannot prove that, I get 0mg/l ammonia and 10mg/l nitrates. However, my problem is that staghorn algae grows almost exclusively in the brightest spot of the tank (middle part) and on stem plants that are near the surface. My lighting setup is 0,5l/w, fresh t5 neon tubes. I tried with covering the middle part of the tank's top glass with baking paper to diffuse and decrease the power of the tubes. But I don't see any improvement so far... I'm also adding DIY CO2. Is there any creature or fish that eats this dreadful algae? I'm manually removing the affected leaves wherever I can, but what I get is just a short-term relief. I have Nerita snails, Otos and Amano shrimps and none seem to eat that... I can't be certain for Amano's, they usually work at night. Or maybe I need much greater army of Amano's to battle staghorn... Any advice would be helpful.
