Can't think it's a good thing Cypography putting a free video out showing Slim Jelley dumping carrier bags full of rock salt into the swim... 
Didn't we go through this once before 15 years ago when Danny Fairbrass was putting a kilo of table salt into his munga?

Been argued time and time again. The general view from people in yhe know, is that the amount of salt you would need to put into a lake to make the slightest bit of difference is literal dump truck loads.

Surely as responsible anglers we should all refrain from putting anything detrimental into our waters ?

Carp may be happy enough in brackish water but if I ran a lake I'd be minded to ban adding salt. Clearly depends on the drainage and size of a lake but if everyone was chucking in rock salt like that think you could pretty quickly affect the salinity of a water. The carp may be ok but you could be killing off plants, other fish species and naturals. All for what, to maybe make it easier to catch a carp? Does salt really work any more than any other bait? - even if it does I don't think it's worth it imo.

The thing is ,one angler throwing in large amounts in a 10+ acre lake is not going to have a detrimental affect .But having a dozen or so angler doing the same on a weedy club lake of 2 or 3 acres is going to alter the water starting off by creating 'dead' zones around those big rocks of salt .

I was studying research by various institutions on the effects of salt in the carps diet ages ago.
In terms of food amounts, 1.5% of the ingested food allowed best growth rate.
Any higher and the body fat content increased, and growth decreased. The 2% diet level of salt resulted in decreased digestibility and faster evacuation of food.
Now this is in food, meals made for fish. Adding salt to particles water may or may not be beneficial, this was not studied; the studies were for fish growth for food, a number of species.

I also saw a (very old) study on flavours / attractors for carp. It was only one study, but salt had no effect at all. Not saying that will always be the case though.

Some people who keep Koi add salt to the water as its very beneficial. Not sure why it could be bad for carp in lakes?

It's used I think to kill parasites

Nicks right, it's used to kill certain parasites but not all, it also helps to promote the mucus growth. It has to be done in a controlled fashion though, too much can be very detrimental and must be totally dissolved before adding to the pond, a pile of salt can cause chemical burns to a fish if it lays on it. It has to be a certain type of salt too, cooking I think as others can contain harmfull additives. I think it is usually recommended that once you're on top of the problem you should start regular water changes to dilute the salt content.
Post 8- I remember seeing that or a similar study, where salt was not deemed to be an attractor.

Do they just throw it in or they calculate amount etc? Peroxide is also used... Should we spomb it out?

It is calculated, as too high a dose is toxic. Hydrogen peroxide is used as a method of algae control. The often quoted method of adding barley straw creates hydrogen peroxide as it rots down in sunlight. Which helps kill off algae.

A small 1 acre lake, averaging 3ft deep would contain over 4 million litres of water. It would take 40,000kg of salt dumped in to raise the salt level to 1%.
Salt may well stay in the water against evaporation, but it will still be exported out of the lake through living organisms, as well as run off. I just can't see it ever being an issue?
