I have been involved in salt water reefing for about 1-2 yrs, unfortunately my tank had a break down due to the lights and I had to revamp everything. I had a few corals perish in that process, My question is the nitrates are at about 80ppm, ive done numerous water changes along w/a vodka dosing method, however I have not seen much change I also have a deep sand bed in my tank I am worried about this due to the fact a member of the reefers club that I am a part of had to tear down his tank remove the sand and start freash.... (I Hope) This is not what I will have to do....
