How many amanos?
I have a 75 gal tank with hair algae. I have another thread about how to combat this... However my toothbrush skills being what they are, I'm pulling out some of the DHG every time I try to clear in. So, I was wondering if I should try to locate some amano shrimp and how many I should get for a 75 gallon. It is moderately planted. Also, are there any specific water parameters I should pay attention to? I have soft water with low pH.
