So I've noticed white particles in the water column. I changed over to LEDs 3 weeks ago and moved Powerheads and rockscape around a little. I also added a bio pellet reactor with Dr. Tim's NP Active Pearls at the same time. I noticed the particles a day or two after those changes. I assumed it was from moving the rocks and Powerheads but it hasn't subsided. Is this normal for the first little while of running a reactor? I thought maybe I had them before and the LEDs just made them noticeable. Any ideas?
