Did you buy the water from your LFS or mix it yourself its best to buy your water for a tank that size then mixing it. Mixing water yourself with nano tanks is fail. You need to run that filter on it. i have a 7g nano thats been running for 4 years I think i have a whisper 10 dialed back on mine no skimmer.
you need to do 50% water changes weekly or every two weeks on a tank that size or death haha
