No, I don't have a cold, it's in my res. I was wondering why the outlet had slowed to a trickle, yanked the pump, and discovered it was COATED with slime. Not a hard fix, just take out the filter and rinse, but I had to TOUCH the slime!!! Who said hydro was CLEAN? Come here and let me smack you two time!! Yuck. Plants are fine though. Almost time to call the system a success and build the other 2 modules.
