Welcome to our forum.
I thought I would jump in and help a moment. Since I have departed the forum it seems many of the more knowledgable industry pros have likewise backed off some. I hope I didn't create that but I would like to help with this one. What you have is a water mold...You need to do a chemical clean ASAP before it continues to grow. The moderator can hook you up with some of the topics that covered this in the past or if you would like email me at cyrano@allvantage.com and I will walk you through it.It seems to be more common in the spring and fall....
The substance is rubbery and has the thickness of a layer of skin. It does not smear when you roll it in your fingers. It is brown in colour with black spots in it. And it is getting worse. The little bits floating around are small...maybe a 1cm or 2 square.
Ouch..... Well, looks like I gonna have to find a new career. I seem to be lacking the microbaterial backround neccessary to excel in this industry.. So.... Signing off for now yada yada yada...... Ok, I'll stay Stuart can very well be correct, as I'm sure he is or he is sure he is (something like that) But to make a guestimation without enough information is hasty. Do these particles smere and break apart when touched or are they of a solid mass? Noing this will help determine if infact it is a water mold, black algae, or "soap poisoning" (Christmas story reference)
With experience comes confidence, way to go Stuart.You're missed by many of us oldtimers!Punked I mean pkud, a little respect would go a long way for you, why don't you try it.Spahappy
