hi,
can you pls help me figure out how to save my fish? i have a 90gallon fish only tank that i started 2 months ago. i read step by step instructions from a website & it told me that i could use play sand instead of live sand & it told me to use south down but i couldn't find it so i bought a brand called sekrete natural play sand. everything seemed fine & after 4 weeks i bought my damsels & they were fine & my water levels were ok.. like week 5 i bought a puffer & a couple days later a tang. i have about 3 inches of sand & i have 2 air bars, a fluval 405 filter & a seaclone skimmer. i have 50lbs of live rock ( i bought it online & was told that it was aquaculterd- ready to be in the tank.) last week i started noticing my puffer was twitching a bit & breathing harder than normal & was a little pale. i tested my water & all of the levels were at their worst. i did a 50% water change & took the water into a fish specialty store yesterday & they said that the nitrites are off the chart. they only suggested that we use stress zyme everyday and do maybe a 10 gallon water change every 3 days. what else can i do?? i really love my puffer & i dont want him to die. i was reading somewhere that maybe he is not getting enough oxygen?? i am going to buy a maxijet powerhead today to see if it helps. do you think the sand could be the problem?? please help if you can |
