Last year end of November I removed, all sand and live rock and treated with copper power for 30 days, at 2.5 ppm. Did 25% water changes everyday without fail (tank is 75G). I use API test kit for ammonia, nitrites and nitrate and Hannah copper checker.
After 30 days, Used cuprisorb and water changes to bring the copper levels down. Around mid Jan this year, I put in washed sand and after a week 1/3rd of the rocks. Then another third the next week and so.
A week back I dosed prazipro. Noticed the spot on wrasse. 2-3 days after prazipro.
Diet:
During copper treatment, I would feed one cube of brine/mysis shrimp in morning and pellets in the evening. The tests showed high nitrites but as I was doing daily water changes it was fine I guess.
After the rocks were in, I setup the automatic fish feeder twice a day and 2 frozen food cubes in the afternoon. I know sounds a lot but thought that was the right quantity. Should I cut down?
I did notice slightly high levels when testing this week. Am I feeding too much? the fishes were active and looked well fed so didn’t think too much about it.
Reading my own reply looks like it was definitely the feeding.
What should I do now for lymphocytis?
