k0olmini Posted September 9, 2022 Share Posted September 9, 2022 I’m going to add crushed coral to my 40 breeder. pH is 6.5-6.8, not ideal so I need to raise the pH and add buffer. Does anyone have any brands they like? Also it’s about 1lb per 10 gallons right? I’m planning on tossing it into the substrate Link to comment Share on other sites More sharing options...
