#ed_op#DIV#ed_cl#Fairly new to the hobby myself so I"m sure someone will correct me if I'm wrong. You should only have @ 1 inch of fish per 5 gallons of water when dealing with saltwater. If you just added all of the livestock yesterday this is probably what caused your spikes. You should add livestockslowly (ie. 1or2 at a time max),so that the bacteria has time to adjust to the bioload that each fish will increase. How old is the tank, what were your water perameters before adding the fish and what type of filtration do you have?#ed_op#/DIV#ed_cl#
