This is Bad. Please Help Me.

Guys this isnt good. I left for a 3 day vacation to go skiing and was called by my brother who told me a fish died. As my tank was established before the move about a month ago i wasnt too surprised. Also before i left i began to run a skimmer through my new overflows. When i came back, i found that 8 more fish had died!!!! all i have left now are a brittle star, a mandarin, a sand goby, and a snowflake eel... (could be dead now). I also has a huge outbreak of brown algae. My params are completely normal and my temp at 79. AHHHH HELP PLEASE! also its a 100 gal

 

A few red flags are popping up from your post. First when you say it was established a month ago, do you mean it was set up a month ago? Or was the cycle finished a month ago? By the sounds of the brown algae outbreak it sounds like your cycle is still either not over or very fresh. Either way it is definitely too young a tank to have that many fish in it. The mandarin will almost surely not make it in a tank that young. I would suggest taking it back immediately. Can we get more specific info about your params and tank history?

 

sorry i wasnt very clear. the tank was established for 2 years before i transported it over to my place 1 month ago. the nitrates are 5-10 nitrate 0 ammonia 0 phosphate low pH 7.8 salinity 1.023

 

Oh ok, not as bad as it originally sounded than. Did you use new sand or the old sand when you moved it?

 

no i used the old sand and it got all mixed up but i assumed that by now it had recovered... obviously not

 

That would be my guess as the problem. Probably caused your tank to go into a cycle which by the sounds of it is over now. Just to tie up loose ends though, I would check your tank for stray voltage and keep a close eye on your params.

Hopefully things will level off for you.
