90p Mini Project

[Suzerolt]

For the past week, I've increased potassium dose whilst reducing macros (Lushgro Aqua)

A couple of observations :
1) Better growth of HC. Brighter green (thanks Blue33 for the tip)
2) No hair algae growth on HC (it was quite a lot previously) - possibly due to decreasing macro fertilizer?
3) Instead of hair algae on HC, I now get greenish algae on the spiky moss instead. Is this called BBA?





And taking into consideration feedback that the current Eheim 2028 is 'over loaded', I've added a 2nd filter (Eheim 2215) and changed the position of the inlet/outlet in an attempt to improve flow.




Comments & inputs welcome.

I would put the outflow of 2215 diagonally opposite of the 2028. Inflow can stay for aesthetic reasons
