Another problem. I went out of town for a wedding and was gone 4 days. My daughter came by once and fed the tank brine shrimp. She didn't really check the stock. When i got home, the first thing I noticed was that my Filamented Fairy Wrasse was missing. I looked everywhere and for speeds sake, I used Strips to check for ammonia and nitrites. i did have .25 ammonia and no nitrites. Since we got home so late, I cleaned the tank 30-35% on Monday morning and later checked the specific gravity and it was 1.023. Most of this i already mentioned. Removed a moderate amount of cyano
in the front and all down the right side, ending in the back. This morning, my Pajama Cardinalfish is gone. i tested and ammonia still read .25, nitrites 5ppm, phosphate 0 and pH 8.0. i don't have a test kit for alkalinity but it was showing 300 per strip. i don't understand why I am losing fish so quickly. the tank has been up since 6/19 and cycled in 9 days. i waited 2 more weeks to put 2 Percula Clowns in there along with 3 corals. i slowly began to add corals each week, but 2 weeks before adding the Pajama and 2 weeks ago added the Wrasse and a neon goby. i clean the tank every Monday and use water from the lfs
. She also provides me with RO
water for top off. the only critters that i have seen coming in on the rock was a bristle worm. i've been told by several people that if i have a water problem the first to go would be my peppermint shrimp. i still have all three and one just molted. i topped off the tank this morning after noting the Pajama was gone. SG
was 1.026 at that time. sorry this is so long, but i wanted to give all the info i could think off. suggestions?
