The leaves of my hairgass is rotting one by one floating throughout the tank- disturbed by a few sword tails. This morning i pulled it out, there is no root at all. What is wrong with it? Is it because of the substrate which is purely river gravel?
I find HC grows better in sand substrate but can be grown in gravel. It needs plenty of light to get established. Once it starts to carpet the ground I find it needs less light but definately needs it to start out. Ferts and Co2 are a big asset when trying to grow HC.
