Hello... I have had my 125g tank up for about 6 months now. I bought a used skimmer from another marsh guest. The very next morning I lost 3 lionfish and 1 trigger. I disconnected the skimmer immediately and still continued to lose fish. I did a 50% water change 3 days later. I also did another 20% last weekend. I bought a couple of damsels that last 5 days before they died. The only livestock I have left from the beginning are my 2 white cheeked eels. Can anyone tell me what could have possibly happened? About to restock my tank in 2 weeks. Thanks for all comments.
