I have just taken over a pool which has been off because of a problem with the SWG controller. This is (hopefully) now fixed (replaced burned out connector) so I would like to get the pool usable again. We are expecting guests in a week so my wife is on my case.
Prior to the SWG problem there was a pool guy who used to maintain it. He used sulphuric acid to adjust the PH, as far as I know that's all he ever added, he said he needed to add a little every few weeks. He stopped coming back in July around the time the SWG packed up. The water was also cleared about a month ago by a well meaning neighbor who was convinced it just needed a shock (before I found the burned out connector). He put in Trichlor and something to make the dead stuff sink and to be fair made it look nice, but with the salt cell not working it reverted to green within a week.
It's been rainy season here for the past month, the pool kept overflowing into the garden so I let out about a third of it, I figured it wouldn't hurt to lose some of the water as I wasn't sure what was in it. The rain has refilled most of it but it could take some more, perhaps another 3 inches. We have a borehole in the garden so no problem for water.
The pool is now very green and murky. I am now hopefully going to sort it out following the advice of this forum
I am pretty sure I need to follow the SLAM process to start with, however I can't find a test for CYA or the FAS/DPD kits here in Thailand. I have just ordered a Taylor K-2006 online but i have no idea if it will make it through Thai customs and even if it does it will take a couple of weeks and if I can do something in the meantime my life will be easier.
So I have at the moment only got OTO and Phenol for total Chlorine and PH. Is there anything I can do with just these? The general consensus here is just chuck in some Trichlor but i'd rather not ...
