Dosing Thrive and Seachem Excel
Temperature is 24 C/75F
My two questions are
1) How long will it take for the Hairgrass to carpet with my setup
2) Will changing my light to the Finnex Planted Plus 24/7 be too strong (it will have a par of around 90-100) causing insane algae? or will it make the grass carpet faster?
Thanks in advance.
You should be ok using the 24/7 despite how shallow the 33 long long is. It is a bright fixture, but a step down in intensity from the planted+. If you run into problems it shouldn't be too difficult to suspend the light to add more distance from the fixture to the tank. You can find full par ratings for the fixture on the planted tank.com. As far as how long it will take the hair grass to carpet your tank, it really depends. I try and plant hair grass in tiny pieces throughout the entire tank to ensure it grows in evenly and quickly. I have noticed that co2
injection really seems to be the secret to success with dwarf hair grass. I have personally never had success growing hair grass at a reasonably fast rate without it.
