Sudden drastic water spike

[Staggy]

i added a Black Widow Anemone 48 hours ago. The day before I did a water change and checked all my parameters everything was right where it needed to to be. I just cleaned the inside of the glass and did a water check of Nitrites, Nitrates, Ammonia, and Phosphates. My Nitrates are between 25-50 ppm.

What is going on????

10 gallon cube with 2 small clowns and a skunk shrimp.

Also for the past 48 hours the anemone has been fully opened up and showing beautifully bubbles. Then one minute it’s open then bam, completely closed. If you didn’t know any better you wouldn’t even know it was an anemone.

Most likely hes filling and expelling water to acclimate to your tank. Not sure on the sudden jump in trates though...
