[theangrycrab]

please someone help...
have already googled and located nothing that is helpful

already lost a clown and now the twin spot is bobbing at the surface and then going back to sand. he is having trouble with buoyancy. please help

nitrates are 0
ph is fine
salinity is getting two different reading from different instruments .020 and .024

is this a salt issue or something i am overlooking??

thank you in advance

Need more info, what's your setup??

[theangrycrab]

oh sorry, thank you answering

12 gallon nano that has been running for 3 months. i had started it with live rock and live sand from another well established tank. i have never had any problems with the tank. corals have doubled in size but i have had two little damsels in there and they look great. i had moved them and put the clown and goby in and that is when it all bad happened. the light is a compact flor. quad 96 watt.

any more needed

yes,

Alkalinity
PH value - "fine" tells little
Salinity do you mean 1.020 to 1.024 ? What do you use to measure salinity?
Amonia
Temp
filtration
what type of freshwater are you using to make your saltwater and where do you get it?

[reeferRob]

Also if you don't have the test kits/tools you should get them but in the mean time most LFS will test yout water for you

[theangrycrab]

will do...thank you reeferRob

i will post my results and go to a lfs in an hour and get them to test also.

just a guess until you post your water test results, but it almost sounds if there is no oxygen in the water and he is surfacing to breathe. Your pump or filter maybe unplugged?

hey rick,

i think i figured it out. the salinity was too high and when i changed it up it worked. i was using a guage that was not accurate. i had dropped him into the 70 gallon and he immediatly was sifting.
it was weird.. his whole body was not just mouth was having trouble.

ph 8.2
kh 11
temp 78.8
nitrate 0
nitrites 0
amm 0
salinity now .024

Good to hear you saved him! If you were using a hydrometer, do yourself a favor and invest in a refractometer. I have killed fish and corals when I first started because the hydrometer did not read right, and I had my salinity WAY to low and left it like that for some time. Might as well have been a fresh water tank! :(
