rsdb is up and going, still need to add 20 more lbs of sand. Did a 100 gallon water change. Also cleaned my sump, not 100% because I ran out of water to flushout the last 1" of dirty water. Maybe some of my issues have to do with a dirty sump. It was loaded with handfuls of what appear to be some sort of worm or worm waste. Can't find anything on it. Its the color of skimmate and resembles string, it was all over the rock and under it, it very easily turns to mud. I flushed a lot of off the rocks and scooped out as much as possible. I always think of worms as being good but not sure if these guys are parasite or what. I added a power head to the sump to keep organic matter from settling on the bottom and hopefully keep in suspension to better skim out. Any help to ID these worm like stuf would be great.
