The questions have only come up once I realized there was a problem. I lost almost everything in the first couple of months after a nitrate spike.Welcome to R2R! Yea trial by fire is always heartbreaking. I remember when I lost my first fish to jumping because I didn't know I needed a lid. He was one of my favorite fish with such a great personality.
Advice I can give you, ask tons of questions! Only stupid question is one not asked!
