hairgrass problems turning brown/blackish and not growing
I have a 125g with aquaticlife light 48in 8 bulb, substrate, compressed co2, and I'm dosing with flourish, my tank as been running for 3 months and everything is doing great but my hairgrass is not doing anything when I got it it was around 2-3in so I trimmed it after a month. Now its doing nothing. And I change the water 1 a week 30% I would put a picture up of it but I don't know how to. Please please help. I don't want to lose all my hairgrass.
