I am actually asking this for a friend who is unable to get online right now. He has a 42 gal. bowfront with a wet/dry and skimmer in the sump. His tank has been set up for about a year but for the last half of the year, his nitrates are spiking approximately every 2 months (it's happened 3 times). His ammonia and nitrites always remain at 0 and NORMALLY his nitrates are around 20 ppm. When the spike occurs, it's usually overnight and will go from 20 ppm to as high as 160 ppm.
Any ideas what could cause this? I forgot, his bioload is:
sailfin tang
coal beauty
percula clown (until last night, died due to the nitrate spike)
yellow wrasse
cleaner shrimp (also recently deceased)
cc star (ditto)
emerald crab
When he noticed the spike, he did a water change (25%) but the nitrates remained high.
Thanks in advanc for your help and suggestions.
