How do i get rid of it

 

[Tahoe61]

How old is the tank? Using RO/DI? Is flow adequate?

Also get a strong cleaning crew, your tank looks young, still adjusting

 

[50gTallnewbie]

It's been running since Jan and no I buy the premixed water and flow is more then adequate

I would triple or quadruple your cleaning crew.
