Opel Fruit<P><BR>Opel Fruit, Dept. 53<P> Posted June 8, 2005 Share Posted June 8, 2005 Filled the autostable with well water (almost potable - just fails on nitrate) and the water has a slight green tint. Not sure if it is algae or not.Have shock treated with combined Algicide/Floc and no difference.Have the tablet chlorine blocks in the floaty thing.Any ideas - I would prefer a "you need to buy this and do this" type answer!!!

Rayring Posted June 11, 2005 Share Posted June 11, 2005 My French hand book on swimming pool maintenance says that green and transparent water can be a sign that the water is too soft. Have you checked the water hardness?What is an autostable by the way. Link to comment Share on other sites More sharing options...
Opel Fruit<P><BR>Opel Fruit, Dept. 53<P> Posted June 11, 2005 Author Share Posted June 11, 2005 The water is soft. The mains water is too, but doesn't seem to be quite as green.There is no algae on the pool sides or bottom - it appears to be tinted water.Autostable is above ground pool.

Baz Posted June 11, 2005 Share Posted June 11, 2005 Green water can often be a sign of Algae being present. The following web page you may find useful to read even if your pool is not as bad as the example.http://www.poolstore.co.uk/ishop/691/shopscr136.htmlAlternativelyWhy has my pool gone green when my test kit says the chlorine level is OK? Your chlorine is 'locked in' by the chemicals used to stabilize it. Granular and tablet form chlorine is bonded to cyanuric acid to prevent it from being burnt off by the sun too quickly. But whilst the chlorine will be used up, the cyanuric acid will remain. Too much cyanuric acid in your pool over stabilizes your chlorine and it cant get free to attack bacteria and algae. You will have to throw out some of the water with the cyanuric acid and replace it with fresh water. Regular and thorough back washing of your filter should prevent over stabilization but in a heavily used pool up to 5%, maybe more, of your water should be replaced each week to keep over stabilization at bay.Baz Link to comment Share on other sites More sharing options...

Opel Fruit<P><BR>Opel Fruit, Dept. 53<P> Posted June 15, 2005 Author Share Posted June 15, 2005 Sorted.ph was below 7.0, so added 1kg of ph plus. Chlorine was above 3.0, oops.Added combined floc/algicide - plenty of it, and it seems to have done the trick. Seemed to have to use more than stated to have effect.
