Hi,
I moved into a house with a pool just over a month ago. Pool was going green as we moved in.
Tried shocking it, but left the pool cover on first time by mistake, so tried again the following night. Still no good.
Someone suggested pH reducer; so added this, and got the pH down to around 7.4, but pool was still green.
Someone suggested that maybe we had a bad dose af algae, and so needed a large shock treatment. Added a double dose, colour didn't change.
Someone suggested flocculent, so added some Jolly Gel to the basket in the pump. Still green water.
Took a sample of water to a pool shop last week, and was told that the pH was 'through the roof'. Suggested that I empty a good part of the pool, top up with fresh water, and add pH reducer to get the level back down again.
Took out around 10 inches of water (perhaps 15% of volume), and so far have added arouind 2kg (4.4lb) of pH reducer. Am adding it at around 1lb at a time, with at least 6 hours between additions. pH is coming down (we are now at around 8, as opposed to 8.6), but pool is as green as ever.
Alkalinity is at around 120, and chlorine level is very low (perhaps 0.5).
Water is very green, even a small sample is clearly discoloured.
Slowly losing the will to live, so would appreciate any advice at all.
Thanks in advance.
1) The size of your pool in gallons30000
2) The type filter you have (sand, DE, cartridge) sand
3) If your pool is an AG (above ground) or IG (in ground) IG
4) If it's IG, tell us if it's vinyl, plaster/pebble, or fiberglass Tiled
5) If you know, tell us the size pump and the size (flow rate) of your filter.Size not known but operating at a pressure of around 10psi
