If you constantly use the same wetting agent, it will accumulate contaminants like chemicals from fixer and as others have said, algae. Just add a few drops to the final wash, just enough to form a few bubbles, agitate and dump. Why folk try and save a nth of a penny on wetting agent is beyond me - I bought my 1 L bottle of Ilfotol in 2007 and I'm still using it!
