    Howzit going?

    I wandered over from TASA when I was looking for a bit more info on aquatic plants. Fairly new to to the hobby, so I'm still reading up, learning and experimenting with the basics. Point in case: my challenge of the week - getting the pH under control...

    I currently have 2 small tanks - a 20l doing a fish less cycle and a 54l one waiting for set up next weekend.

    I hope to pick up quite a bit of info here on how to treat plants correctly - rather than just ' stick-'em-in-the-ground-and-hope-they-don't-die '.

    Hi and Welcome!

    BTW, is you pH fluctuating a lot?

    Thanks, guys.

    @Chongkie , I did a 75% water change. The pH drops from 9 (straight out of the tap) to about 8.5 (after I add Seachem Prime as per instructions) to >5 in less than 12 h...
    I suspect the substrate or possibly the piece of driftwood I have in there... if its not either, I'm stumped. I could probably fix this by adding some water treatment, but I'd rather adjust the filter media or the decorations or... does anyone have any suggestions?

    0.5 isn't bad, it's actually very normal. pH of Tap water is normally higher, and once you aerate it, it should drop a lil. Nothing to be too concerned about.

    Rather don't tinker with the pH with additives. If u have driftwood, it will bring the the pH a bit down, but it won't bring it drastically down.

    @Chongkie i'm not really concerned about the o.5 drop after i add water conditioner - I'm concerned about the 3.5 drop that happens after that. Ie the drop that brings the pH down to less than 5.

    Welcome Sible,
    This does not make sense.
    I have experienced the water coming out of my tap to sometimes be quite high, up to 9; -but after leaving it standing for about 24 hrs, it is a perfect 7.
    I suggest you leave it to age in a drum or bucket for a day or 2 without adding anything first and see where it levels out.
    Also make sure your test kit is reliable.
    What area of Cape Town are you from?

    @JCL

    Thanks, and I agree it doesn't make sense.

    I'll give your advice a try. I have water ageing - treatment free. ( I live in Blouberg, BTW)
    I'm using the Tetra pH test - according to the guy at the LFS its supposed to be ok.

    Also - I removed the drift wood and did another 75% water change last night, and same problem: the pH of the water I added was about 8 - this morning I tested again, and I have a pH of 5. o_O

    Time to experiment with the substrate - maybe that causes the alkalinity... if that's not it - a plant maybe? Is that even possible?

    Welcome to APSA @Sybille ... as mentioned above, age your water before you add it to your tank, so the pH doesn't drop and shock your fish. What substrate and filter media do you have in your tank?

    Cape Town has soft water (maybe you can give us your TDS reading?), which makes buffering rather difficult. Maybe some crushed coral in your filter will help, but give us some more info regarding your setup first ;)

    Also note...the smaller your body of water, the quicker external factors have an impact on your water. For instance, it's much easier to keep 500L stable, than 10L.

    Agree fully with @JAX, age your water outside your tank and test the pH before adding it into your main tank.
    You need to eliminate one by one the causes for this.
    I find it very strange that after a 75% water change your pH would go from 8 down to 5 in the space of a night. :confused:
    Please give us more info on the substrate and filtration you are using, as well as your general set up and stock list. Or are both of your tanks still fish less?

    Thanks @JAX an @JCL

    Found the issue. Its the substrate. I am using this stuff:
    [​IMG]

    Is it possible that I'm using it wrong? I basically just plonked it in and added plants and water. Does anybody have any experience with this particular product?

    You'll have to speak to the Cape Town guys, we up here in Gauteng wont/dont touch BlackEarth. Apparently some guys down in CPT has had some success with it, so I'm sure they can assist on how to use it.
