Epson 10000 Yellow HELP PLEASE!

Hi Everyone,
I have an Epson 10000, and my Yellow head is clogged up. I have printed many great images off this printer, now everything is purple. I did a head check and yellow is all blocked up. I have tried running head cleaning about 50 times and no change. Any help would be greatly appreciated.
I am useing CGS ink not by choice but it is what came with the printer.

 

Isn't there a cleaning fluid that you can run through in extreme cases of clogging?

 

I dont know if there is, but if there is could someone tell me where to get some and how to use it?

I did a deep cleaning on the printer and now I have no color coming out of the M or Y
