have you tried seperating the clumps of dwarf hair grass before heard they spread faster in smaller clumps but, not sure haven't tried dwarf hairgrass yet.
Everything looks great, im really impressed with its progression. I have a couple of questions though, as i have a 55 gallon planted as well. Ive had some great growth but also great hair algae growth as well, do you get a lot of algae as well? And how do u take car of yours if you do? and is Co2 important? I have read things multiple things that are for it and against it
I only usually get green dot algae but when I do get hair algae I od seachems excel. I also think that co2 is important for keeping alga under control and if you have a lot of light
