    how much kalkwasser must be added per litre top up? or is it dependent on your tanks rate of calcium absorption.

    It is irrelevant. You add a couple of tablespoons of kalkwasser, then stir it well. Let it stand for an hour or so in order for all the undissolved kalkwasser to fall to the bottom the container. You only ever want to dose the dissolved, clear water.

    Thanks

    The top up pump must pump through a kalkstirrer filled with a bit of kalkwasser. It has a closed loop pump mixing the kalkwasser every few hours.

    Not sure if you can source them in SA but here in sunny London, the Tunze osmolator top up unit is the bee's knees. Cost about £130, so that should be around R1400. Well worth it in my opinion :thumbup:

    I got the same unit for LFS in Durban, was round R600

    forgot to mention that the pump is TINY, it will never draw water from ground level to a display tank, its only strong enough to get water to a sump on the same level as water tank.

    I dont have a sump so I had to replace the pump with a 12V bilge pump (like used on boats)

    you can do the same by getting a float switch from RS components in midrand for 80 bucks and a small pump for 100 bucks. thats what i did.

    it works like a dream.

    I'm using about 3L top up per day in my nano, it seems like a lot is that about normal?

    125L so 2.5% a day?

    Yes it is normal. You will have more evaporation in winter as well. I go through about 40 litres a week.
