Nerites, angels will eat amanos.Ok. My lfs has nerite most of the time and Amano shrimp sometimes. I have tetras but an angel in the tank. Which would be best a nerite or Amano? I have mystery snails in that tank also
Having said that dont expect them to eat it all. The best defense against algae is balancing nutrients with light. Too much light not enough of the correct nutrients equals algae too little light too much nutrients equals algae.
Try to figure out the imbalance and tweaking that.
Bba is usually from excess phosphates most algae problems according to tom barr are due to problems with CO2 or excess and or ammonia. I think weve already established your diy co2 wasnt doing you many favors
