Algae in water filter

We are snowbirds and stay 4-5 months in Florida with a city water hookup that has a typical filter with a charcoal filter in place outside that catches the sun. Recently I noticed the water pressure starting to drop and thought at first it water pressure in the park but soon discovered when it got quite bad (water pressure) that is was a problem with green algae clogging up the water line at the filter. It had been replaced less than 3 months ago. I replaced it and ran Clorox through the system and things seem to be fine now. This has never happened before in over 40 years of RV'ing and I am wondering if there is something further that I should or could do? Is there any way to prevent this happening in the future. Are we in any danger from the algae in the water?

    The green algae is fine but it's metabolic waste products can be unpleasant, and cause gastric upset.

    Some algae species also emit toxins as a defense to kill competing plant species. Again not dangerous to humans but can give you digestive problems, or if your health is questionable already perhaps more severe complications.

    Blue-green algae on the other hand is actually cyanobacteria and not a plant at all. It produces a wide array of toxins including neurotoxin, which are harmful to humans and other higher life forms.
  • It may not hurt you, but it will clog your filter, reduce the carbon filter life, and make your water taste awful.

    Part of the function of the carbon filter is to remove chlorine. So any water standing in it is likely NOT chlorinated at that point.

    I agree that shading it with something thick/dark enough to block sunlight should be an adequate solution. You could wrap it in some heavy aluminum foil, and crimp it down snugly. That would be less likely to blow away than a towel.

  • Since you have already corrected it, I would suggest you shade the filter so you dont have a re-occurance A towel or something placed over the unit should suffice. Normally city water has enough chlorine to avoid that problem unless the usage is low.
