    Hi Guys,

    I've not dosed for about a week, poor husbandry on my part :-(

    Anyway, what to I get up first ?

    dKh = 6
    Ca = 390
    Mg = 990
    Ph = 8.4 (daytime, full lighting)

    System vol about 320L

    Should I first bring up dKh or Mg, I'm sure Ca is just about ok, but I do have a few SPS ?

    @Sammy .hey

    1 magnesium
    2 alkalinity
    3 calcium
    4 pH

    Once magnesium and alkalinity is up, ph should adjust itself, so no real need to buffer unless its wayyy out ... Calcium you can do with kalk, mix up a batch and drip the clear water in over a certain period, not sure of the dosing amonts for your size aquarium, do it daily but gradually.... Check your dosing instructions as I'm not too sure but certain doses is prefered in the mornings followd by evening doses... That's what I know so the experts can jump in and elaborate on that .....

    Hi there,

    Thanks for the help, i'm using:

    Mg - Epsom Salts
    dKH - Sechem's Reef Builder
    Ca - Seachems Reef Complete or slaked lime as kalkwasser

    So I'm first going to get the Mg up with a teaspoon of Epsom Salts a day ???, then move on to up the dkH

    You can dose the alkalinity first as that is critically low. After a few hours add some epsom salts and the following day up your calcium as it's low but not critically. Dont be tempted to add the alkalinity and calcium at the same time to prevent precipitation

    Just used the reef chemistry calculator and it says to raise mg from 990 to 1300 in a 320L tank I need to add, 978g of epsom salts, could this be right ? its almost a kilo ???

    Sounds much and just being cautious ?

    Also can I up mg and alk the same time, or do I need to do one first???

    Raising mg using Epsom salts does take a lot of Epsom salts maybe get hold of some Magnesium chloride, would be faster. To raise the rest you can use kalk, using the slurry method.

    @ALLAN, thank for the answer, so what will be the max recommened epsom salts (in g) to add to my 320L per day ?

    Also would you mind explaining the kalk slurry method ? (I normally just mix 2 tsp of slaked lime in 2L RO, let it stand for about 20mins and drip slowly into sump overnight ?)

    You could more than likely add 200g Epsom salts per day, personally i would try get mag chloride.
    Slurry method is a little scary, but it works as you add equal ALK and CA. You will have to do the research though as i cant remember the dosages off hand, here is how i do it. I add 2tsp kalk into 200ml ro water stir up well and pour solution into main display in front of circulation pump, no waiting to settle out, remember my system is almost 3000L. I have been doing this for about 3yrs now with no side effects. When you pour the solution, pour relatively slow and consistent, the display water clouds up a bit, but will clear in about 5 min.

    @ alan, I can't argue with experience ,but for a newbie.... I would recommend the drip method,its much safer,mix up ur kalk on the same manner , leave it to clear an then drip the clear water in over an hour period..... That will assist in raising ur calcium aswell.... I think stick to what's easier an more simple for now, use proper methods like seachem reef builder an then those after market product methods like epsom salts,kalk an so on... Use those to rather maintain....

    Yeah, I must admit, does sound scary, I will opt for drip method ?

    Anyway, as per Seachem calculation, I was told I needed 48g reef builder to raise my alk by 2. Decided on to dose 24g so I should expect and increase of + 1dKh and tested this morning my alk has shot up to 9.5 ?

    So my question is, I only expected and increase in 1dKH and instead I got almost 4 ? Why so far out when using the instructions on the bottle ?

    ??....Please explain?


    As for the dripping of kalk, it will never raise parameters the best you can hope for is maintain parameters even then you may need a kalk stirer or reactor.

    Very interesting, but does this happen with Epsom Salts (Magnesium Sulphate) as well as Magnesium Chloride, by the looks of things its Magnesium Chloride. Might be safer just to by a well known Magnesium additive.

    Sammy all should be fine, appears the problem lies with Magnesium chloride not Magnesium sulphate. Keep a check on the magnesium readings every day or so.
