45 pH Test Kit
Get one; these kits are extremely cheap, so there is no excuse for not
owning one. You will want to know the pH of your tap water so that you
can select fish whose requirements meet your water conditions. In
addition, you will periodically want to check your tank's pH so that
you can be sure it stays stable and doesn't increase or decrease
significantly over time.
In some cases, tank decorations (e.g., driftwood) or gravel (e.g.,
made of coral, shells or limestone) change the pH of your water. For
example, tank items may slowly leach ions into your tank's water,
raising the GH and KH (and pH). With driftwood, it is not uncommon to
have the wood slowly leach tannins that lower the pH.
