    don't for get also to ensure you Mg is ok, to maintain their stabilty all 3 should be at the desired levels else you will battle.

    Here's some handy info I find extemely usefull in understanding the chemistry: http://reef.diesyst.com/flashcalc/flashcalc.html

    Please remember that when lifting you ALK,MAG,Cal that this should be done slowly and not all at once.

    You cant rely on kalk to keep KH and calcium at the desired level. One parameter will get depleted faster than the other. Get a calcium additive to raise your ca to the desired levels.

    Roderige - the alkalinity in the tank, is to ensure that the pH swings in the tank, does not have too much of an effect on the lifestock.

    Calcium on the other hand - feeds the corals, and corraline algae.

    I have always used kalkwasser to dose my tank. But - keeping calcium stable is only really achieved with a calcium reactor.

    You will still have some calcium level swings - up and down. But - believe me - your corals actually adapt over time (very slowly) to YOUR tank and YOUR feeding regime!

    KALK has a very low solubility in water, so it doesnt matter how much you add only so much of it will dissolve. You generally add about two teaspoons to 2litres of water and only drip the clear liquid and not the precipitate (unless you doing slurry method).
    Overdosing on KALK will have more efffect on your KH than upping your calcium. Rather use a calcium supplement to raise the levels and KALK to maintain them BUT you will need to occasionally add additives to keep ca in check.

    How many times would you recommend using the left over white stuff in the bottle after the first does ? Or must I throw it away and make a new batch ?

    The "white stuff" Roderigo, is a compound of calcium carbonate. Calcium, reacts with carbon-dioxide in the water, which frees the creates the complex compound calcium-carbonate. This is not the same calcium-carbonate used to buffer the tank with, as it is insoluble.

    You can use it as "substrate" if you want - and when this gets to the lower regions of a DSB, it would most likely be broken down again.

    choose a drip rate and monitor parameters closely for a few days then adjust the drip rate as needed. Drip rate will depend on what you have in your tank.

    If your kh is fine and you only want to increase calcium, then use a calcium supplement. Increasing kalk will increase KH and calcium so wont really solve the problem.
    The amount of kalk youll have to dose to raise calcium by 50 will have shocking effects on kh and pH.

    Just to add to this:
    Adding kalk to your tank does increase your pH! Just be careful that you don't push your pH up too much....
