I'm aiming for 3-6KH, 2-8GH and a consistent pH of no more than 7.5 in an 11g (44L) planted tank. My tap water parameters are 6.8pH, 1-2GH and < 1KH. I've used powdered buffers in the past, but have had great difficulty maintaining consistent GH / KH / pH following water changes. I see that many have better luck with a natural buffer like crushed coral.
1. Are there any issues using crushed coral to maintain the right GH + KH levels for a planted tank?
2. Are there types of coral that are better suited than others?
3. How much should I use?
