  1. I have seen in the USA a product called jack's magic blue stuff which removes copper and allows the filter to collect it. Has anyone seen this, or anything like it, in Thailand ? Normal copper stain removers remove the copper but it is still in the water (filter won't trap it apparently) and at some point it will reattach itself to the grout again. If I have to use a Thai copper stain remover (and then drain the pool I suppose), does anyone have any recommendations? Always good to use one that is known to work ! The problem I reported below may be the copper algaecide I used. Adding lots of chlorine afterwards to try to get rid of the staining may have made the situation worse and turned the stain black. That would make sense. All help welcome
  2. Yep. Instructions on the tub were in Thai and had no idea it could cause so much havoc. What does confuse me is that the PH is always low (as I understand it the chlorinator works better if PH is slightly low) and still was after I added the algaecide. The only time the pool has had high PH was when constructed and the builder had a PH of 8-9+ and was dabbing algae with chlorine tablets. As soon as I saw this I got rid of him and had to put in a lot of acid to get it back to neutral. do you know anyone in HH who can do a good job ? I am quite happy to buy all the materials.
  3. After having had no issues with the pool for many years I have a sudden huge outbreak of black algae. Free chlorine at spa+ levels, PH about 7. After very heavy rain I always chuck in some chlorine granules (salt water pool) as extra insurance. I then decided to add for the first time some algaecide. Blue stuff. Must have copper in it as the concrete overflow went green. As did the grout. Cleaned to waste a couple of times, and then a week or so later after more heavy rain the pool went black (including the plastic fittings) in a couple of days. Free chlorine levels still very high, PH about 7. Still not sure how it all went black. Scrubbing at the top level black stuff with an aluminium brush is taking a lot of grout off (it was crocodile platinum). Looking at my options I think a complete regrout (incl acid wash after removing the grout) would be the best way forward. Replace plastic fittings in the pool. Replace sand in filter. Pool is 12 * 4 * 1.4m. tiles are 10cm What kind of price would I be looking at, or, indeed, can anyone here recommend anyone for a quote. I am in Hua Hin. Thanks.
  4. I am flying to Chiang Mai from Hua Hin in a couple of days. The airasia website says i should look at the destination for details of what i need. I have looked and looked, I cant find details , but i do have an old list from facebook that says only 1 AZ required. No mention of antigen test. Is that right ? I have tried contacting Air Asia , but after 90 minutes and finally getting through to AVA, the connection, from their end, timed out after i explained the problem :-( Anyone any experience of flying into chiang mai or has a link to the current requirements. Thanks,
