Right this morning came down to my tank and first thing I did was my API test. So ammonia was up and so was nitrite. I don't know what's causing this!! I got a new filter from fish shop and it was already seeded and I'm wondering if this is causing this spike. My tank has been going a month no issues but I have done a 50 water change and they all seamed happy. Advice please guys ??
