The person has 10 gall tank and ph and everything was normal but alkalinity was high..is this bad? Is it possible to fix?
Hi, medical science student here.
Alkalinity is a measure of how basic, as opposed to how acidic your water is. If the water is too basic, or alkaline, it is "hard"; if it is acidic it is "soft". A pH scale is used (it's a logarithmic scale) from 0 to 14. 0 to 6 is acidic. 7 is neutral. 8-14 is basic, or alkaline. As a comparison, gastric juice (in your stomach), which contains hydrochloric acid, has a pH of about 2-3. It's a measure of how many hydrogen ions (acidic) or hydroxide ions (basic) you have in the water. An equal amount of hydrogen ions H+ and hydroxide ions OH- = a pH of 7 (neutral). Bettas prefer slightly softer water (which is what tannins do to it).
PS: To lower the alkalinity, tell them to get pH Down.
