My fish keep dying but my water tests come out perfect! i have had my 30 gallon tank for over a month just did a water change last week and vacuumed my sand, can anyone give me a clue to what is going on.

i have just got over (i pray to god) exactly the same thing, tell me what your water tests are reading, salt, ph, temp, nitrate, nitrite, amonia, and the fish you keep, i think i no the answers to all your problems

if your tank is just over a month old and you've had several fish die already, perhaps your tank has never cycled yet; that is why your fish are dying. no ammonia--get new fish-- new fish breathes and defecates--ammonia with not enough bacteria population to convert to nitrite and nitrate--fish die. just a thought---consider letting your tank sit for a bit and feed your tank with leftover fish food to help propagate enough bacteria. You should see some test results too. good luck.

thank you,my tank is about 3 months old, my tests are of last week Nitrate 80, Nitrite 0, Ammonia 0, pH 8.3, Phosphate 0.1, Alkalinity is fine, Calcium 410, Salinity 1.022, Temp 77 during the day and 76 at night

What is in your tank for cycling. Live rock, dead shrimp. Did you do the water test before the fish died or ofter the water change. If it is after the fish died, then I would have to agree taht it was an ammonia spike and the tank is not fully cycled.

Just something to think about......Read my thread, "I NEED HELP" I just went thru the same thing.....What is your water source? I was using city water and recently found that my city is using 3ppm chlorine and I am sure that was my problem. I might be way off track but I wanted to put it out there.

I dont use city water, i buy RO water from the LPS. I think It might have just been a spike like the last person said since it is a young tank. But thanks to all of you guys for trying to help me.

Like i said before i just wanted to thank all of you guys for giving me alot of info it has helped, none of my fish have died since seems to have been just a spike and everything seems to be going well thanks a million.
