Ok, so I had a week were I was so frigging sick from pregnancy that I ended up on three prescription medications just so I could keep food down. They actually gave me a drug they give to chemo patients to keep me from throwing up. Anyways, enough of the sob story, I didn't do a water change in my nano that week to say the least. Well now I have attack of the killer hair algea, because I started to feel bad for the fishes but I didn't have the energy to go to foodlion and buy distilled water so I did a water change with tap water. Big mistake, not sure what happened but I assume it's high in nitrates and I lost my two shrimps and my emerald crab and now my tank has hair algea. This was my first loss of any kind in this tank and now I have been back on a regular schedule of distilled/ro water changes and cleaning but the hair algea keeps coming back. Whatever should I do?
