    Hi all.

    Hope all is well.
    First Q: What would the dosing ratio of the DSD be on a 1ft tank? The tank will only have anubia and vallis with plain silica sand and some pots (clay)

    2nd: I saw some lava rock at Burmisters for R150 for 1.5kg. Will it work as a filter media and is this a good price? I think it was for a fire.

    Thanks guys!

    I have some lava rock sitting in my store room collecting dust. Please come get it if you are in JHB and you want it. There is quite a lot, and it is perfect filtration media. It may buffer your PH though.

    Hey thanks @Sean J, but I'm in East London and won't be going to JHB in a loooong time. Thanks again for the offer.

    If I remember, its 10 ml per 100 litres. So assuming the 1 foot is 12litres, you would initially dose 1.2ml. If you do a 50%wc, you would add 0.6ml.

    Thanks @Zoom
    If I do bi-weekly water changes, can I add the DSD once a week?
    Thanks again.

    Rather split the dose into 3 parts and dose 3 times a week. Every alternate day with a rest day.

    With regards to the Lava Rock though, it will buffer the PH... I remember that @neilh had it in his tank and it definitely buffered his PH, that's why he gave it to me.
