Black mold on walls

I finally decided to deal with what I'm convinced is at least partly mold.   My idea is that the dust from the top of the wall washes down in the rain and sticks to porous paint.   The constant summer time moisture then turns it to mold.

All flat paint may not be as porous as the next but I've used a number of brands and qualities of paint and most of them watered to some degree or another.  The inside of this one meter wall on the roof is stained the same way all around which makes me think I used the same paint. None of the house outside walls have this stain .... so maybe paint quality.

My treatment, which I think it needed, was to scrub twice with a brush, spray pure cloro the next day and then paint it with undiluted exterior semi-gloss.   The new paint is actually shiny so I assume less will stick to it or absorb into it.  The catch is I'm finding out what a real good paint job costs because this paint is expensive. Still much of the house that never gets wet so I don't have to paint it all at once.

Keeping the pool clean in this heat

A few weeks ago the water temp went through the roof and started turning green. That's the first time in over 4 months. I gave it a good hit of Shock and surprisingly it was clear the next day. Now I just give a hit of Cloro out of the bottle every morning and it's doing fine even with big crowds.

I gave up doing the chemical testing for PH and CL. It just didn't seem to be doing anything for my knowledge or helping the pool. I will get some more Shock but adding acid in any form was just a waste of time and money. I stopped by the local pool store to see what could be done for vacuuming and the kid that works there gave me the best tip. Just get about 4 meters of 3/4 or 1" hose, get it siphoning and suck out the stuff on the bottom. Good excuse for me to get into the pool.   Every time you vacuum the level goes down so a chance for some fresh water. 

Cleaning a cistern

Every now and then you need to clean your cistern and I was totally unsure how much mud and sand was in mine. All I knew was that the intake valve was often plugged after non use of my pump and the first bit of water was always dirty. The first year the system had no filter for water from the street so I thought it might be serious but there turned out to be less than an inch of mud. My intake valve is 4-5 inches above the bottom so how it got plugged I don't know.

I drained most of the last 5 inches with a bucket and then we lowered a neighbor in and he finished the job with a sponge, rags and a little cloro. I imagine with double filters the cistern will be good for 3-4 years now.
