    Now for some chemical questions. I have SERA test kits(Milli - look away) and the results tonight showed: Calcium 420-440 ; Nitrates 20mg/l ; Carbonate hardness 6'dKH and ammonia/ammonium 0 mg/l. How accurate are these SERA test kits? What kits do you guys recommend and where do I get them? The nitrates and KH worry me a little - can I sleep sound with those figures? FYI - I use R/O water.Can not measure my PH yet - Millipora?:whistling:

    Never used Sera test kits so I can't comment on them, I use Salifert. I believe Tropic Marine test kits are very good.

    Nitrates isn't too bad if you only have fish, if you have corals in the tank you will want to lower that as much as possible.

    dKH of 6 also isn't too bad, quite acceptable although 8-12 is recommended.

    How do you lower the nitrates except with a water change(which I'm doing 2morrow)?
    How do you raise the dKH?

    Dilution is the solution to the pollution (as Mr Anthony Calfo says)

    Waterchanges will lower the nitrates, as will a mature DSB, which can take a few months to become fully functional and effective. So for now regular waterchanges will do it.

    If you want a cheap method of increasing your dKH, pop in to Pick 'n Pay or wherever and get yourself some Bicarbonate of soda. I am not too sure on the quantities you will need to dose, someone else will have to help you on that, or have a read through this thread...http://www.marineaquariumsa.com/showthread.php?t=1454

    Just remember whenever you are adjusting your parameters, do it slowly, over a few days, not all in one foul swoop.

    Regular water changes, and don't feed too much, also allow your rock to mature and don't stock too quickly. As long as everything else is sweet, a bit of nitrate isn't too drastic.

    Live rock, DSB and a sea weed in the system will all lower nitrates.

    I have compared the sera kh to the Tunze and they are also the same. Just did not know how good the Tunze test kit is.

    I do 10% water changes every 2 weeks, my live rock has been running for 18 months now(came from my previous system) and has got a lot of life on them, there are also a pot load of pods in the rock which comes out at night. This tank ran with water from old tank for about 2 months with 1 fish and a cleaner shrimp, then I added 2 small fish every 2 weeks. Got 5 in now, all eat well and very active.
