    Hi chaps,

    I have lately been topping up mt system with RO ware in a 25 litre drum containing at most 10 teespoons of slaked lime (chemist grade) I let it run into the DT very slowly but even if I let the undisolved lime settle for an hour or so, the water still goes cloudy. I had 4 goldies and theay have now all die and I beleive it is as aresult of the topping up method described. The slurry method would surely also have the same effect on the system, so can anybody comment as to the possibe reasons for the goldies dying and a more safer way to top up considdering the less hardy stock one might have?

    Thanks,

    a few Q's

    how long you had them?
    why run it into the DT, no sump?
    how much you toping up at a time?
    salinity of tank water now?
    were they eating properly?

    to make it easier make an auto top off unit

    I use the slurry method with no ill effects. Daily I mix 1 teaspoon Kalk with 1 litre RO. Shake and dump the mixture in the skimmer compartment

    I have had them for a year and have doubled in size and ate very well with multiple feeds a day. I run the top up into the dt from the 25 litre drum I place on the canopy and slowly gravity feed in via a thin tube. I do have a float activated auto top-up in the sump and RO unit in roof above. The kalk adding, mixing bit I have not got resolved yet hence the manual way. I would top up about 15 to 20 litres at a time. Salinity and all water params normal or within safe ranges. I'm quite certain it was the top-up that killed them as it happened immediately after the water had gone in.

    that would make sense, but why now?
    any other livestock in the tank?

    take the dead fish and place them in a container with fresh cold water, and see what falls out the gills? maybe a parasite etc

    Ok, to be exactly correct in answering, I never used to put kalk in my top up water and struggled with all sorts of algal blooms. Since adding the lime, my PH is mare stable and the blooms have gove. I suspect that the goldies being quite fragile fish they could not handle the fine lime in their water. A better option would clearly be to top up more regularly with smaller volumes.
