Thanks for the advice. I am a little confused though. I was of the understanding that pure AS lacked the N (and P?) that is contained in PS, therefore requiring water column ferts right away when using pure AS.
So AS contains lots of N and P then? I assume it must do if plants grow well with no requirement for additional dosing (except K), especially with no fish food/waste to provide any. I guess I'm so used to "overdosing" via EI it goes against my instinct to have such a lean regime.
What would dosing EI from the outset do? Cause algae? Even with 30ppm CO2 and high bio-mass, fast weeds? Or are we just talking waste?
Good to know I don't need peat. When describing mulm is it literally just the waste "gunk" from old substrate? Any tips on separating it from the gravel? Would squeezing mature filter sponges over the bottom help too, I assume its a similar substance.
Or I could just add some PS or PS Special eh? lol |
