    Default Water chemistry

    Can someone please make a list and post the proper chemistry levels we should be at in out tanks? Example Nitrate =0 -.10 Ph 8.0-8.2 and so on. I had a reference list but I can't seem to find it. I tried to search for them but I wasn't finding what i was looking for.


    Thanks a lot.

    Angie

    Ammonia < 0.01 ppm
    nitrite <0.1 ppm
    nitrate < 25 ppm
    PH 8.0-8.5
    temp 72-80
    sg 1.021-1.026
    Ca 350-450
    Alk 9-12 dKH
    Phos 0
    There's nowhere else I'ld rather be... unless, of course, you're buying

    How about Iodine/Iodide for inverts and some coral?

    1-2ppm sound reasonable?

    I know some softies thrive on it, how about SPS varieties? Anyone know if they have any demand/need for it?

    Thank you Repto. I appreciate it.

    How do I raise my alk? I tested yesterday using a salifert test kit and it was 8.0 dkh or 2.86 meq/L. I know it is not severly low, but I'm still having problems keeping my Calcium up.

    The next test kits being ordered are mag. and phosphate.

    Thanks,
    Angie

    Angie, to raise the Alkalinty, we go the cheap route, baked baking soda, I add 4 tsp's per day any time the alk drops below 9dKH, I just mix it into a 2 gallon top off and drip it in. (just until I get the new top auto top off built)

    By baking it, you remove the majority of CO2 from it, which in turn helps reduce the raising effect on PH. I do large batches at a time (several boxes), spread it out on a cookie sheet and bake @450 degrees for about an hour, store as airtight as possible (gallon ziplock bag works great).

    I understand washing soda will work as well, but I haven't looked for it around us so haven't tried it yet, not sure what the effects on PH are either.

    PH buffer is a 5:1 baking soda:washing soda. C02 will actually lower PH. Washing soda will fire up your PH quite quickly, though(hence the mix... doesn't effect PH too badly... more for the Alk. Washing soda is baked baking soda. Angie, sounds like you may need to keep up a bit more on keeping your reactor charged(PH of 12-12.5)... with evap and auto kalk top-off, you should find that your Ca/Alk levels are more stable. BTW, test your mag levels, too(1300-1300). Ooops... sorry Whoyah... I see you got that covered.

    I like to use NSW S.G. 1.026,lots of synthetic salt mixes are low in Magnesium and by mixing full strength,the levels will be higher.Baking soda will slightly lower PH as mentioned by Repto,I use it unbaked 2-3 times a wk.As well as Calcium Chloride to balance the alkalinity provided by baking soda.12ml of liquid calcium(kent) is what is needed to balance out 1 tsp of baking soda.Alkalinity(bicarbonate/carbonate) is the limiting factor in calcification in stoney corals.Many test calcium often and strive to keep it at 420ppm.By monitoring alkalinty depletion,you can pretty much tell where your calcium is at because they are tied together.Once the 2 levels are balanced it becomes much easier to maintain without much testing.I only test calc monthly and its been at 420ppm,i test for alk 2times a week(in my new tank)and by adding a balnced baking soda/CaChl supplement,the levels have been consistent.
