In your sig, the issue is plain as day and laready mentioned, high light, cheesy CO2.............
Get better CO2 system, a 10X better co2 diffusion method, ladders suck, fun to watch, but they really do suck
No dosing is going to correct a CO2 issue really.
Less light and better CO2, those are the main issues, nutrients are frankly very easy and way over rated.
Plants are 50% or so carbon.......... higher light= more CO2 demand.
It's not all about nutrients, there are other factors, that is why folks liuse things up with every dosing method for nutrients, there are folks that do well and a lot that do not.
It's not the method that fails, it's the user and why they think they have troubles. Some never accept CO2 as an issue. I'm always amazed at how folks(in general) will fuss over nutrients ad nauesum, but brush off CO2 without a second guess
Do not ever do that.
I can easily disprove a direct cause for nutrients and algae.
Easily................and so can others...............
We cannot do that for light easily and certainly not somethign as variable for measurements or the temporal changes for CO2.
We can mss with our CO2 and induce algae easily with higher light, so you do the math.
This is common sense, but often gets lost on many.
