I recently decided that rather than continue to pay a poolguy to service my pool, I would take the time to read up on and understand whatwas actually going on in that mysterious container of green-blue water in mybackyard. Therefore, after reading quitea bit around the forum, I bought a test kit and started working on turning thegreen-blue into something that was at least clear a lot less green. I startedthe SLAM last Friday, and based on the numbers and the look of the water I think I should be at the "magical 3" in the next couple of days. Along the way, I started to understand a little bit about not only the chemistry but also the hardware, so...
As I look at my pool's circulation system, I see what I believe to be the skimmer, a side-suction port (where the hose for the automatic cleaner attaches), and two main drains in the bottom of the pool. I currently have excellent suction on the side-suction port, with a bit less on the skimmer drain, and no detectable suction on the main drains. While I can increase /decrease the suction on the side-port and skimmer by adjusting the handles, I have yet to figure out a combination that brings the main drains in to draw anything. As I would like to get the mains involved in clearing out the post-SLAM debris, I thought Iwould see if anyone might have some pointers.
Iím attaching a couple of pictures in case that will help in understanding my set up.
