    Guys

    I browsed throught the TOTM history, and came across SunnyX's SPS system - FEATURED SYSTEM - OCTOBER 2009. It really is a beautifull setup. I read that he used the Calcium, Alk two part solution described here: 404 - Not Found

    I got rid of all my softies, and want to start on SPS's.

    Has anybody tried this solution in SA?

    Thanks
    Chris

    Yes, I have. I think a fair number of people have used it.

    Chris, this method happens to be one of the cheapest (after the Slurry Method) yet effective ways of dosing calcium and Alk. Many international reefers use it, im sure you have viewed their TOTM's on Reef Central.

    Thanks Mekaeel - you using it as well, or used it in the past? I love your SPS setup, by the way. Something to work towards.

    Hi Chirs. Thanks for the kind words :)
    Yes I did use it in the past, but found it a bit too much of a headache to mix and dose, so I stuck with the Slurry method which works just as well. :)
    Ideally, the two part solution should/can be run using dosing pumps.

    Hi Chris. I also check Sonny's system out this holidays. I think his got the most beautiful tank out there.
    Here is his blog: Rimless Reef - Rimless Reef 2.0: the dawn of the new Rimless setup!
    And here is his thread on Reefcentral: Sonny's Rimless Shallow Reef 2.0 - Page 12 - Reef Central Online Community

    I want to do what he does.

    I think we must use this thread to work together, what do you think?

    Well, I checked the 2 part solution out and opted to do the following:
    Dose, Seachem Calcium - because it also contains magnesium and strotium.
    For alkalinity - use baking soda or Seachem PH 8.3

    I told the local LFS that I want to do what Sonny do and he said there is to much unknown's. It is so confusing because I want to keep my alkalinity at 8 and calcium at 420 but he said its to high. I must test the seawater, because I use NSW, and stick it that levels.

    The LFS guy needs to do a coarse in reef keeping before passing comments like that. NSW levels, Ca : 380-420 and Alk: 6.5 - 8.5 DKH.

    Thanks Mekaeel. He is quite a boffin and knows what he is talking about with many years of experience. I realized with reefkeeping, its not as cut and dry as with pc's. Experience and patience is the name of the game.

    NSW is also variable depending on location. If he was suggesting that you mimic local chemical parameters then that was simply bad advice. I've measured Ca as low as 320ppm, Mg as low as 1100ppm and routinely depressed alkalinity in local waters.

    Target the numbers Mekaeel suggested, and also check your magnesium is around 1300ppm.

    My 2c on slurry vs two part. Get your parameters to where you want them using two part, then use slurry for maintenance. If alk and Ca get out of whack again, correct using two part.

    Ok then - I saw some threads on the slurry method - will study these awhile!

    Boegie, I will report back on what I find
