    Just wondering if anyone is still using this as a Kalk replacement?

    The brand from the original post of Bunnings thing you can use doesn't seem to be available any more

    There is 2 brands at the moment which I can see on the website anyway might be different in store,

    Adelaide Brighton Cement Lime https://www.bunnings.com.au/adelaide-brighton-cement-20kg-hydrated-lime_p0760175
    85-95% calcium hydroxide, other trace stuff is magnesium hydroxide (assuming this is fine because mag is usually in salt water anyway) silicone dioxide, aluminium oxide (0-2%) and iron 3 oxide 0-0.7%

    Main question here is the aluminium oxide and iron oxide going to be detrimental in the long run? Also the ingredient list seems to differ from the Bunnings website to what is on their actual website.

    Other option i found was the Dingo brand - its listed as 90-95% calcium hydroxide and doesn't even list the remaining 5-10% so not sure which one I'd be better off trying? https://www.bunnings.com.au/dingo-1kg-hydrated-lime_p0760508

    Or is it just best to play it safe and stick with aquarium grade stuff?

    Have the coral box dosing pump arriving next week hopefully so would like to set up a channel for kalk at the moment while my tank is low demand. Having it in the ATO is a bit up and down depending on the day
