Mrs Wages Pickling Lime, same powder you buy at the lfs but a whole lot cheaper.
Wow thanks Bro ... I think I am heading up for cheap charlie style and save $$$ for new corals
Seriously, I have just bought a 6 heads dosing pump ... Do you know a good alternative for 'Pickling Lime' or 'Kalkwasser' but in liquid form ?

What is Kalkwasser?
Put simply, it's the German translation of "œlime water" or "œchalk water". You may have come across lime water for example in chemistry practical classes at high school. But for whatever reason, it's the German name that's become established in the marine fishkeeping hobby rather than the English names used in science and industry.
Kalkwasser is formed from a solution of fresh water and lime. Commercial kalkwasser powder is sold at a tropical fish shops, but there are alternatives. Many marine aquarists find pickling lime, calcium hydroxide, to be just as safe to use as commercial kalkwasser powder, but much less expensive. Another type of lime, quick lime, can also been widely used. Quick lime is calcium oxide, but when mixed with water a certain amount of heat is produced, so some caution is advised when using quick lime.
How does Kalkwasser work?
The complicated chemical reactions can be easily found in books and technical articles in fishkeeping magazines, but for the sake of this article, I will try to keep things as simple as possible. Advanced aquarists may consider what follows an oversimplification, but I won't tell them if you don't!
The kalkwasser solution contains water, calcium ions and hydroxide ions. The calcium ions obviously help to raise the concentration of calcium in the water, a good thing for animals and plants that use calcium for their skeletons. The hydroxide interacts with dissolved carbon dioxide to form bicarbonate, and together with any remaining hydroxide ions, this raises the alkalinity, thereby buffering pH and inhibiting acidification.
