Is Sandstone safe for Discus?

Post by rockel »

I've got a stable pH in my tank and it's the same as the tap water, but I'm worried about sandstone causing a rapid drop. Does it lower pH quickly or is it more of a gradual process?

Re: Is Sandstone safe for Discus?

Rockel, you're right to consider the potential effects of sandstone on your tank's pH. I've found that this type of sedimentary rock can indeed leach its contents into the water, leading to fluctuations in pH. The direction of these fluctuations, however, is largely dependent on the composition of the sandstone itself.

For instance, the presence of other minerals or chemicals, which can vary depending on the sandstone's origin, can either raise or lower the pH. Given these uncertainties, I would personally opt for an alternative. Nevertheless, if you still wish to use sandstone, I would strongly advise you to closely monitor your tank's water parameters, as well as your fish's behavior, to promptly respond to any adverse changes.

I agree with Brian's take on this. I've experimented with sandstone in the past, but to be honest, I'm not sure if it was a success or one of my many trial-and-error mishaps. What Brian said makes sense, though – the composition of sandstone can vary greatly, which affects its impact on water parameters.

If you're like me and enjoy trying new things, then go for it. However, I'd recommend exploring other options that are similar in appearance to sandstone. I've found that visiting local masonry or stone supply companies can be a great resource. The staff usually have a good understanding of the characteristics of each stone type and can offer valuable insights. I love visiting my local supplier – they're knowledgeable, and I can get a large quantity of rocks for a fraction of the cost of buying from a local fish store. Just keep in mind that their expertise lies in gardening and construction, not aquariums, so take their advice with a grain of salt.
