gutter water tinted

[mrcrow]

its been hot and my conservatory gutter has dried out
it usually due to a bad incline set up has about 20mm lying in it in wet weather
it rained quite heavily recently so the 20mm re-appeared but
it is tinted a rosy red colour and some dripped out of a joint at a corner and dyed the window cill below...which took some cleaning off
is this a dangerous algae in the atmosphere or normal...the usual is some algae which is black
cheers

It's a normal algae - often found in commercial dishwashers - must be the heat in your gutter
