How to make my PH go up?

[Canterthefishman]

I went on vacation and my brackish water tank's PH went so low it killed my archerfish and my mono, so I need to get my PH higher I wanted to know how.

Thanks

To do so naturally ... use crushed corals, limestones and or Marble. I'd recommend you not get any pH chemicals.

I use crushed coral as sand. Ok thanks.

I'm curious, why would you being on vacation make your pH alter so drastically?

I do not know maybe my fish feeder dropped to much food in and rotted. But I do not know.

Crushed coral is a great way to go, my water is soft SA/CA heaven but I like my africans and this is how I keep them happy by adding it to those tanks.
