    My pool pump 1.5 HP for 8,000 Baht, bought at a pump specialist - not a pool specialist - no problem over many years. Similar pump (or maybe the same with another name - Chinese product) I saw is now on sale separately also at GH, few sizes. Also their filter is OK - I am having over 15 years, working even after flooding.

    Copper Sulfate can be bought at chemical shops for 150 Baht/kg sack.

    My simple DIY equipment and the daily experience for my daily swimming throughout the year I have described in my post in Construction section, where actually this discussion belongs.

    Also describing handling of my troubled source water (very strong ironized) what in all literature is as impossible for swimming pools.

    Spending many hours studying what is available re pools, found so many rubbish, mostly with the hidden agenda (of the ones who run the show): buy what we advise you. Otherwise, our shops go bankrupt (with CS care and no pH care)...

    Vacuuming - and backwashing - I cannot think to do it just once a month, especially when using the wonderful floculator/disinfector SaanSom. When seeing the outlet I am having onto garden (what obviously not everybody can see - direct somewhere into a sewage?), seeing after few days what's going out. Thru such a filth I should force my good water for one month long?

    If you decide to try using copper sulphate in your pool,you mix it in a bucket of water until all the crystals have dissolved, pour it into a garden pressure spray the larger the better and spray it over the entire surface of the water in your swimming pool
    Still no sign of algae in our pool, it works
    About 4 years ago i bought a 4 litre container of algaecide from a swimming pool company for 1250 baht on special with no list of ingredients on the container but it was the same colour as CV mixed in water and only for one treatment of the pool
    I can make the same amount myself for less than 100 baht

    The thread is nothing about construction, its about algae in swimming pools in Phuket so its in the right forum
    I have not vacuumed our pool since starting this thread, i just asked my wife if it needed doing and she said no, and i agree with her
    IF you want to vacuum your pool every 3 days that's fine with me, vacuum it daily if you want to
    I bought a 25KG sack of CS of Lazada for 2250 baht delivered ( enough to out last me) 90 Baht a KG not 150 baht a KG
    No reason to get upset if someone does not agree with you, this is a public forum after all
    Have a nice day

    We have had a lot of heavy rain recently, for one period of 48 hours almost non stop which had diluted the amount of CS in the pool and the algae started to come back
    I put another 200 grams of CS in the pool and it was gone in 4 hours
