So about a month ago I woke up to my filter spewing water all over my floor. Filter was done so I got another one, went up a size, and seeded the new filter with older material. All levels in the water were good and now all of a sudden this week my nitrate levels are ridiculously high, maybe around 80ppm. So I did another 50% water change three days after my weekly and got it down to atleast 40ppm. Going to do another one tomorrow to see if I can get it lower. I would do a 100% but I live in the desert and the tap water is coming out hot so I am having to bucket my water and let it sit to room temperature over night and I don't have enough buckets for a 100% change.
I did notice this white cottony stuff on my moor's tail. Is it the starting of fin rot? And what can I do to fix it?
