Something nasty in the swimming pool ...

And you are no doubt the rocket scientist of the family, but then you don't seen to have a clue what to call yourself.

employee to opportunist to employer.

my dad said he wanted to name me /mark/ but he quipped that "mark" sounded like a dog with a hare lip.

what you see is what you get.

Fr sake, its the alcohol, not the chlorine level you need to increase. Around 15% IIRC.

Dead rats are an essential part of cider making allegedly, so look forward to a vintage year ;-)

Not where I live, the reservoir is almost empty :(

Can't hosepipe ban, see above.

I've been advised by a pool company to get the Cl to 15ppm and circulate for 8 hours. So I've doubled that.

"The hosepipe ban will apply to watering plants and car washing at residential addresses, but there will be no restrictions on using a hose to fill up a swimming pool"

Pools aren't covered. The BEEB was going on about it a day ago.

Only car washing and plant watering.

Just got a reply from the Leptospirosis Information Center

"The free chlorine levels in typical public pools (2 to 4 ppm) are sufficient to kill all pathogenic leptospires given enough time. The standard data comes from a set of studies conducted in the late 1950's (Alston J & Broom J, Leptospirosis in man and animals, Livingstone Press London 1958), which proved lethality within 45 minutes at

3.5ppm. Also, with a private pool there is less volume exchange than public pools, so a 2 to 4 ppm level would be more than adequate for safety."

It's lemmings that do that.....

[Mike Halmarack]

I suppose a deadly drop can open the door to an improved environment for some.

[Bob Martin]

That's a myth.

[Chris Bacon]

Really? Why do you think that?

[Matt]

Carry on like that and you might end up wishing your wife was a barrister rather than a microbiologist.

[Hzatph]

I agree with this. Too high a level of chlorine, particularly combined with a low pH, can lead to chloramine formation which is not pleasant for swimming.

[The Medway Handyman]

Simple solution then - fill the pool with lemming aid.

I'll get my coat.................
