    With Kalk/ Slakedlime

    Google DIY KalkReactor, or slaked lime. you can then get an idea of how to increase your KH

    Cheapest way is to use baking soda.

    kH? Bicarb of soda. Quintin - slaked lime will increase calcium - and not kH specifically. bicarb of soda is use to increase kH (the "hardness of the water" - basically the water's ability to stay stable, without too high pH swings during daytime and night-time).....

    BTW- slaked lime also increases pH!

    Bicard of Soda - yes. Can come in a blue box at your local supermarket. It is usually used in baking, as per Viper's comment. Just don't use WASHING soda.....

    Strange thing I noticed lately..... Have always used one brand, and only in the last two weeks switched over to the other..... Cannot remember which I used first and which now, BUT what I noticed is that the latest one (the one which specifically says B.P. Quality) is a lot less solluble than the other brand.......
    Have been t busy with other stuff to really get into it..... Actually wanna do a mini thread on it some time......

    Ivan - have you investigated getting this from Protea Chemicals directly? They have a factory shop in Killarney Gardens.

    Time..... Time..... Time....... work 9am to 9pm and doubt if their warehouse gonna stay open for yours truly... The "do you know who I am" speech don't work everywhere......

    And besides, the stuff at Shoprite is cheap enough not to have to want to buy in bulk....... I top up with "spiked" kalkwasser and do the shortfall in dKH with bicarb...
    @leonspanner , bicarb will do just fine, IIRC, 3g will increase alk by 0.8 dKh per 150 Litre tank volume. One should not add more than this amount per day in a tank housing corals. Commercial brands often advocate that you should not raise Alk by more than 2 dkh per day, which is fine in a system containing only fish, but in a reef tank, slowly is everything...
