Highing ph

[AquaBarb]

Aww man I am going to end up fully living my tank dreams through you haha! Make sure you check out other Tanganyikans that can go with Frontosas as there are some stunning fish when you start looking. I really want a Tropheus tank at somepoint.

Dont give me more options lol im struggling to chose already
just looked up Tropheus....wow!!! beautiful fish

Carbonates abdd bicarbonates are what makeup KH in tanks. Kh is what keeps pH high. Limestone, crushed coral sea shells etc. are all able to raise KH. They do it because they are dissolved by acid and that will raise pH.

Raising and Lowering pH​

One can raise or lower pH by adding chemicals. Because of buffering, however, the process is difficult to get right. Increasing or decreasing the pH (in a stable way) actually involves changing the KH. The most common approach is to add a buffer (in the previous section) whose equilibrium holds the pH at the desired value.
Muriatic (hydrochloric) acid can be used to reduce pH. Note that the exact quantity needed depends on the water's buffering capacity. In effect, you add enough acid to use up all the buffering capacity. Once this has been done, decreasing the pH is easy. However, it should be noted that the resultant lower-pH water has much less KH buffering than it did before, making it more susceptible to pH swings when (for instance) nitrate levels rise. Warning: It goes without saying that acids are VERY dangerous! Do not use this approach unless you know what you are doing, and you should treat the water BEFORE adding it to the aquarium

Hardening Your Water (Raising GH and/or KH)​

The following measurements are approximate; use a test kit to verify you've achieved the intended results. Note that if your water is extremely soft to begin with (1 degree KH or less), you may get a drastic change in pH as the buffer is added.
To raise both GH and KH simultaneously, add calcium carbonate (CaCO3). 1/2 teaspoon per 100 liters of water will increase both the KH and GH by about 1-2 dH. Alternatively, add some sea shells, coral, limestone, marble chips, etc. to your filter.

To raise the KH without raising the GH, add sodium bicarbonate (NaHCO3), commonly known as baking soda. 1/2 teaspoon per 100 Liters raises the KH by about 1 dH. Sodium bicarbonate drives the pH towards an equilibrium value of 8.2.
