    I have the two part and want to start using it but first I am trying to get my alk to stabilize,
    my mag is 1400
    cal is 450
    alk is 2.7
    I raise my alk to 3.6 then by the next day its back down to 2.7.
    is this normal?

    Remember that Cal and Alk work against each other and Mag stablizes the two. Have you tested your Nh3 and No2 lately? Luna

    acually no, you mean ammonia and nitrites? I'll check them now.

    I did just check my No3's and finally after being 5 ppm they dropped to 0.
    Also I am adding almost half a gallon of ro/di water a day due to evap.

    Also, it depends on the dosing amount that you are using too. Are you dosing equally? Luna

    yes I am dosing 30m/l of each a day. something like .6 m/l per gallon.I just started it 2 days ago.
    I dosed this morning then about 5 hrs later I checked my alk and cal and it was at:
    cal 450
    alk 2.7.

    well my nitrites are .1 all I can figure is I just did a 15% wc and siphoned the crushed coral on the bottom which has caused a mini cycle.

    I added my first daily dose of the same thing today. It took me a week to get my numbers up and stable - after I initially added the first big dose to bring my numbers up it took it almost 5 days before they leveled out/showed a meaningful rise).

    My coral load is real light so I'm adding the .2ml/gallon in my top off water (3gallons of TOW at a time) more like every other day (currently takes about 2 days to need 3 gallons top off water) - still working on dialing it in.



    It is havoc on my skimmer. I had to raise the cup WAY up. hopefully the daily dose won't do the same thing. Keep an eye on that too.

    You could try a buffer or a water change. Looks like you have improper ionic balance. Stop dosing calcium for a week and see if the alk. is still going down.

    I just checked my mag again, wow it's 1600 ,I screwed up somewhere in the testing before.
    I checked it twice and it is 1600.:(

    edit: ok its 1360, I had to use a different test tube due to the build up in the one I was originally using.

    Get your Mag to 1500 and make sure your Cal is between 400-450. Then your Alk/Dkh should be between 8-12. Luna
