My husband and I went out of town on wednesday night and tank looked fine. Everything working properly. My sister was babysitting at our house, and so my son was in charge of turning lights off and on and putting a pinch of food in tank daily. Apparently, there was a noise where sump and protein skimmer are early sunday and then making a really loud noise sunday night so my sister turned everything off because also water was all underneath where sump is. The rock and sand have turned a rusty color (see pics). They couldn't contact me until this morning(mon morning) and so my husband instructed her to unplug protein skimmer and turn everything else back on. Just got home tonight and so far see one dead snail, dead peppermint shrimp and haven't seen one of the emerald crabs. Long story short, my tank is a new setup see my "info". Just got the lights 10-14 days ago? I checked water parameters nh3
5, ph 8.4, phospate 0, salinty 1.25.
Am I having an algae bloom? What should I do? I don't know when the peppermint shrimp died, could it have been from everything being turned off for 12hours. Where I found it, it almost looks like it got stuck between glass and rock. I tried to remove it and now it is in the back of the tank and I don't know if I can't reach it. Will hurt to leave it in there?
I know this is a lot of questions, but please help. We were planning on getting fish next week but now it looks like it's going to be awhile.
