+1 for GFO, -1 for pellets. IME, they strip the water too quickly and I experienced some bleaching from them. In addition, many people, including myself, have had increased cyano from the pellets. I'll never try them again.
You could be using them wrong. Too many pellets, or tumbling too much will cause an excess of bacteria leading to the issues listed. You should try again, use less pellets, and try a newer reactor designed for pellets to get them tumbling just right. I couldn't be happier with biopellets, and coupled with GFO makes a great pair for nutrient control. I love being able to overfeed without worrying about it.
