I was doing regular brushing and vacumming shores this morning and I found the jet returns were light brown tinted inside. I also noticed that the water pump basket has the same coloration in the upper middle section. I wonder it this could be some sort of algae?
This may explain an unusual chlorine consumption for the latter days.
By the way, my current levels are:
I expect a lot of bathers this weekend so I decided to use some extra bleach last night.
I've been reading a lot about algae but never seen it in real life.
Also as you might see here, I've lost some of the small pieces of venetian tile, some of the white space have turned either brown or black, could this mean algae too?
So what do you think?
Thanks in advance for your commments.
