Dwarf hair grass browning

[Blueskiesdz]

I've had to reduce my twin t5 ho to one 39w due to algae on my new (3 weeks) 36x18x18. I've noticed the dhg has brown blades and wondering is this due to the reduction in light or the fact it's now submerged ? I'm now using EI in the last week and co2 has always been on the tank.

Any advice please ?

Did you watch George's video?

I had DHG in my tank and every time I changed something more light/ more co2 I had some melting. it usually recovers though

Hi Alto no I haven't I'll take a look.

Big Clown thanks I've reduced light so perhaps that is causing the problem.
