Hi all,
Current LS: 15 corals, 8 fish (1 new as of this past Saturday). Red Sea Reefer 250

Here's the breakdown of what i did this past weekend (1 new fish + refugium):

1. Saturday 6/15
   1. Added a Mandarin Dragonet on Saturday 6/15
   2. Created refugium in sump (Baseball size chaeto, 8x8x4" Marine Pure block, 3.8Oz of Bio Spira into block, w/ return pump and skimmer off). I did add an H80 Kessil light and powerhead in refugium as well
   3. During lights out, added one 16 oz bag of tisbe pods to tank, and two bags of tisbe pods to refugium (with return pump, skimmer, and refugium power head off for an hour)
2. Sunday 6/16
   1. Did a ~20% water change (~10G)
   2. At lights out added another 16 oz bag of copeopds to tank, and 3 16oz bag of copepods to refugium (same process as above)

My feeding has been normal (half a block of frozen cube twice a day). So, my question is.. My nitrite is at 0.2ppm today and i have not fed the tank yet.

Should i be worried and take action?

Here's my testing for past 3 days

I wouldn’t worry. Changes of that magnitude will have some effect for sure.

Thanks for responding! I appreciate your help. Can i feed the fish with 0.2ppm nitrite or wait and retest for 0 before feeding?

I might do a small water change if you haven’t already. But if your tank has been up a while, the bacteria will take care of all of that stuff. Feed your fish conservatively.

You are ok to feed at .2ppm
