    So my new tank is a bit low on Calcium - was reading 325 two days ago and so I started to dose with calcium and it is now sitting at 340. I would like to get it somewhere close to 400.

    The questions are:

    1 - What is the recommended daily dosing amount. I am currently dosing about 300ml per day over a 4-5 hour period (drip dosing)
    2 - Once the 400 level has been reached, I assume dosing can stop, but would I have to start it again once it drops or should daily dosing be an ongoing thing ?
    3 - Which of the other minerals should I be looking out for in particular ?

    Thanks

    first off, never increase more than this for each in a day, Ca = 20ppm, Mg = 10ppm and Alk = 1Kdh

    You will need to keep all three in check, remember corals etc will use all 3 so you need to get them to the correct values, then measure 3 days in a row at same time to get avg daily consumption then dose accordingly, once every 2-3 weeks depending on stocking you will need to readjust dosage etc.

    Ok, so the corals etc use up these chemicals - therefore this is pretty much an on going process .... makes sense. I have Calcium for dosing at the moment (will get other stuff soon) so I will dose at my current 15ppm/day until I reach 400ppm. Then will take 3-day readings and adjust as required.

    Is there a way to measure what your solution (I use calcium chips dissolved in RO) will equate to in ppm ? or is this guess work ?

    Ok, the label says "add half a teaspoon per 500litres of water" .... my system is 400litres so just a little less than 1/2 teaspoon then. My question is: can I add this full amount (just less than 1/2 teaspoon) to a vial (about 1 litre) and dissolve the calcium and then drip it into the sump. Is that ok to do that way ?

    Yes, I use a 2l coke bottle to make up my calcium concentrate and then add it over a couple of days or as and when needed.

    what is the strength? how much will 1/2 a teaspoon raise the Ca?

    if it doesnt mention that, not worth using IMHO
