hey all, i have an ro/di filter and I left the filter sitting on my counter for a while and now I have algea growing on the cartridges. I test the water with my TDS and it still reads very low, like less than 4 ppm, and the water pressure is still around 45psi, however I'm not sure if I should just trash all the cartridges and buy new ones or if it's ok to continue to use these. they are all less than a year old. what do you think?
thanks, gW
