Need to raise the ph in my malawi tank and have read that baking soda will work . Does anyone have any experience in using this and how effective it is and also how safe it is , I dnt want to harm my fish to save a few quid .
Thanks

Hi all,

Yes it works OK. People don't normally use it for planted tanks because of the sodium content. Potassium bicarbonate (KHCO3) or potassium carbonate (K2CO3) <"are the more usual ones">.

Because you live in Colchester can't you just use your tap-water to add some hardness? Lake Malawi isn't like Lake Tanganyika (where the water is <"very strange and mineral rich">).

I wouldnt be planning to put it in my planted tank just my Malawi tank . My tap water comes out at 6.5 which is good for plants if I'm correct ? I dnt have plants in my Malawi tank just need to raise the ph. This is just a planted tank forum I've just realised

I agree with the others I'd be absolutely amazed if that was the pH after the water had sat for a while. You should be able to get hardness values for your tap water from your water company.

The problem is that pH is only a really useful measurement when you have some measure of the water's carbonate hardness. I'd really like to know the water parameters of my tanks, but it is a <"lot more problematic"> that most forums and websites would suggest.
