    HI,

    Are you sure your calcium is 280 ? that is very low and should be 420-450.

    What test kits are you using ? what type of filter materials ?

    I will also increase the waterchanges to weekly to help bring nitrate down but maybe with a better quality salt..

    You've given 2 different readings for your Nitrate?
    If it's 4.5 then there's nothing major to worry about, it's an acceptable level, especially as you only have LPS and soft corals. If you've been struggling to get it down for over a year then perhaps try a different test kit just to make sure.

    As Jacques pointed out, your Calcium is very very low, is the Calcium Reactor running or are you only doing the 2 part dosing? If you're just doing the dosing then you need to double check you have the correct ingredients/quantities or perhaps a faulty test kit, especially as you are dosing daily?

    Yes, the calcium is 280. I test every week. I am using Sera test kits. I have checked the expiry dates on these just in case. The calcium reactor is running and I am dosing as well. I have already checked the recipe to ensure I have made up the dosing solutions correctly. I just can't raise the level.
    I made an error on the nitrate - should read 45mgs/l.
    I will buy some new test kits. What brand do you recommend?
    Tks for suggestion to do water change every week - no Christmas holiday for me, hey?

    Sorry, forgot to mention the filter system. I had a Fluval filter until a year ago when I changed to 2 deep sand beds in sump and about 2inch sand in display tank. What salt do you recomment? I thought SERA was good?

    Salifert Test kits are mostly used and you can have a look at Tropic Marin as well..

    Can you tell me how deep your sandbeds are ?

    Salt ill either change to Seachem,Tropic Marin,Deltec,Brightwell all good salts with the correct amounts of calcium.

    I would first test the calcium with a new Test kit to make sure its at 290 because it looks suspicious because your Magnesium is almost where it should be.

    Let us know what the new test kit says

    Thanks you guys & gals. I am blown away by your quick response. My 2 sump sandbeds are 140mm and the display tank sandbed is 70mm.
    I will continue thread when I buy new test kits and re-establish where i'm at.

    A cycle period is 6 weeks. If the tank crashed a year ago, then those rocks should be fine by now.

    Just a shot into the dark.
    What substrate are you using?

    Jurgen has gone off to Sam's to buy new test kits. I will find out what substrata - I just remember it was very expensive. I have managed (I think) to load some photos with the Image uploader. Hope you can all view them. I am unfamiliar with how to save them in the proper place.

    to the reluctant but involved wife, the rock structure up against the back will cause some issues. You will not have enough water flow around and under them and will cause dead spots.

    Either re-stack to open up a bit, or put another power head behind the rock work, just to create extra flow, blow out detritus settlement and prevent dead spots.

    i agree with RiaanP, the rocks and deep gravel in the tank might be causing some of the nitrates.
    do you clean the gravel at all?

    maybe use a power head to "blow" behind the rocks to clean things etc

    There is a Tunze pump behind the rocks on the back glass of the display tank, blowing left to right. We use a turkey baster and sometimes a powerhead to blow off the rocks before we do the water change, and we also suck the detritus from the gravel. However, we have now discovered that the underlayer of gravel is compacted so probably anaerobic. Possibly too deep a sandbed, what do you think?
    The rock is too densely packed and does touch the glass in quite a few places. We will have to do a re-build.
    Re-tested with Salifert. Nitrate 50; Kh 8.2; Ca 320. Jurgen also bought Seachem De-Nitrate and has put it in sump.
    He can't remember what brand of sand he bought for the sumps but it is sugar fine.
    He thinks it is coral sand in the display tank.

    What carbon are you using? Is it proper Granular Activated Carbon? If so, how often do you change it?

    To be honest, your tank and all livestock looks really good.

    Yes, it is a granulated carbon bought at Sams. No brand name = clear plastic container with red lid at R69.95 each. I change it once a month.
    I have decided to take out most of the gravel and re-scape the tank. Have to eliminate the 'dead spots' under the rock. I have checked out the MASA section on aquascaping and feel inspired to make the changes.
    Thnk you.

    so you have to post an after picture.

    Do not remove the gravel in go. Take out some. And 2-3 days later a bit more. Until you have the amount you want in the tank.
