Hello TFP Members!
I have been reading your forum for sometime, so I thought it was time to introduce myself, and thanks you for all the useful information I have read here!
I own a 70,000l ~ 20,000gal pool in Tucumán, Argentina. The pool sits near the house with is itself in a mountain lader. That means that some walls of the pool are overt the land. I decided to make 4 windows in the pool, 2 look to the garage and 2 to a living room downstairs. I am attaching some photos. It took me almost 2 years to find a good solution for sealing the windows But they are OK now.
Also, the pool has a infinity border, which I (badly) design myself. This season I added a 1000l (340gal) tank to fix the catch basing design, and it is finally working OK. I will be happy to assist any member of this.
I am working now on DIY acid feeder. I will post photos later.
Thanks a lot TFP!!
