My tank has been setup for about a year and half. Used tropic eden live sand, i use rodi
water, I havent had a diatom bloom until I added about 10 pounds of dry rock. I use 2 mp10s on my 55 gallon. Use Marineland reef capable led
's with timers. I havent had a diatom bloom in about a year. Could that dry rock kick start a diatom bloom? Is it really a such thing as a Old sandbed syndrome? Should I take the old sandbed out and put a new one? I siphon the top layer of my sand and have been for a year and half. I'm lost cause I have no idea what started this bloom. No hair algea or nothing. Just diatoms.
