I now decant my developer into 0.5L PET plastic Coca Cola Bottles.

I pre-fill the bottles with Tetenal Protectan before pouring in the Dev to help minimise oxygenation during filling

Seems to work a treat

And, with my daughter home from Uni for the summer, I seem to have a never ending supply :rolleyes:

Don't keep any partialy filled bottles - I just dump it at the end of the session
