Hi
I seem to have a few difficulties with my 360 L planted tank.
I'm not in a bad spot, but seems growth is slow and some plants (red plants) struggle a bit.
About a month ago, several plants started growing curly leaves, and colors turned from red/pink to deep purple.
As I was never really satisfied with flow from flowheads, I installed another external filter and added spraybar along the sidewall.
The last couple of weeks, I've tuned in CO2, to the point where fish a few fish was gasping at the surface, and I turned CO2 down a bit.
According to PH, CO2 is good and stable when lights come on till lights off.
Been doing EI since start of setup, about 5 months ago, mixing solution from dry ferts and dosed daily.
Issues started, as I added fish and started feeding, which I guess changed the balance a bit, and I started seeing some algae.
I turned down the light, and upped the waterchanges to 2/week at 50%.
Now algae is not a big issue. Just a little on the fuzz on the glass after several days, and som GSA on some older leaves.
Question is, if the lack of growth is because of the low, maybe too low, light? Could it be lack of nutrients, because of the increased waterchanges - a combination?
I have no PAR data so can't give other info than watts and lumens.
I'm not sure if I should increase light intensity and/ or maybe ferts?
Let me know what info is needed. I feel a lot of this planted tank is also trial and error.
