Hamp Posted February 23, 2011 Share Posted February 23, 2011 KH swing, or PH I would think. How long since you tested your water or did a water change? How long were you gone? Quote Link to comment Share on other sites More sharing options...
JamesL Posted February 23, 2011 Share Posted February 23, 2011 Also, check your Mg levels. I had lots of issues with Acans when my Mg was low. Quote Link to comment Share on other sites More sharing options...
Timfish Posted February 23, 2011 Share Posted February 23, 2011 Were you gone during the cold front we had? I had the Birdsnest in 2 tanks lose most of the brown pigmentation in two systems that dropped to 70 - 71 degrees. Nothing else was affected and it didn't kill the Birdsnest they're just noticably pinker without the brown coloration. As far as the "bugs" if you haven't added anything in a while without dipping I'd say they're most likely benificial and just scavaging food not the cause. Since you've had some dieoff I would expect it to have some impact on your water parameters. It can be a guess sometimes if a dieoff caused a change in test results or if something caused a change in parameters that negatively impacted the livestock. Obviously a water change is in order either way. Quote Link to comment Share on other sites More sharing options...
teg Posted February 23, 2011 Share Posted February 23, 2011 Monitor your alkalinity and pH over a week to see if it swing, like Hamp said above. Quote Link to comment Share on other sites More sharing options...
