Raising gh without raising tds

[logi-cat]

Is there a way of raising the gh of water without raising the tds? Im aiming for 4-6 degrees of hardness, at the moment its around 3. Is that ok for crs?

Any component dissolved in the water automatically increases Total Dissolved Solids. That's why it's called Total Dissolved Solids.

Hi logi - what's your tds at please? Your gh is not far off perfect at 3, maybe raise to 5 in ideal world. I use mosura mineral plus to increase my gh but it will also raise the tds. If you have low tds, you might be able to stand increasing it a little anyway.

You'll need to do a water change with some water of lower TDS, but sufficient mineral content to avoid affecting your other parameters. It'll be tricky, but achievable.

I use GHbooster from plant nutrition and it raises the tds only slightly while getting my gh to 6 from 1.
