Gary, I think you may be on to something......its the only swirled cap I have.

I have two other larger flat caps that seem to be doing great.....

I dipped it last night........
I do add iodine about every 14 days......about a cap full......Felipe said that stuff is VERY stong....

I have done water changes regularly....and good ones......
I will double check all the paramenters tonight or tommorrow and just triple check for any problems.....

Mike
