Yes, not sure what the cause, I went away for almost 2 months, and had to ask my family to take care of my tank, thats what I came back to, plus lots of hair algae -my nitrates were up a little when I got back, but I did water change right away, and my water param. have been good ever since. I've narrowed it down to 3 things,
1.) They topped off, with my regular water instead of the ro, they swear they didn't not sure if I believe them.
2.) they didn't feed the algae sheets everyday like they promised.
3.) could be a long shot, but our house was hit by lightning while we were gone, all the televisions were damaged, fridge, chimmney, lamps, almost anything not on a surge protector. The tank lights were damaged as well, I'm surprised the tank wasn't fried, but all my fish are still alive, but after reading some of the post about stray voltage I was wondering.
Now that his momma is back I hope it clears up soon. I'm thinking of trying the zoecon to help. Never had to use that before and I had him for 2 1/2 yrs.
I'll post pic when he gets better.
