    Hi, new to saltwater reefing, today I tested my levels and found my nitrates were really high 100mg/l but ammonia is 0mg/l and nitrite is less than 0.3mg/l. So I immediately did a 30%water change and still no different, I checked my new water I put in before too and all levels were perfect, the tank has been running since November 2017. Any help would appreciated,.. please don’t be mean... :(

    Is this a current photo of your tank? There’s no alge growth like you would see with nitrates that high. How old is your test kit? Did you repeat the test?
