I have to say this every now and then: It does not matter how much your scrubber grows; it matters how strong your scrubber is. They are two different things. Two huge wrestlers can get into a lock-up and barely move, because each is so strong. But if one of them is just a little weaker, and gets pushed backwards a little... then he goes over the edge. Going over the edge would be "green growth", even if just a little.Do you guys thing this is good harvest from 16G tank in 6 days ?
Today I have new wave of ciano invasion.
Your cyano... or any other display "problem", is just from a weak scrubber. Either give it more time to "push back", or make it stronger.
From the growth you have... dark but no yellow... you need stronger lights.
Ah yes, if you do a water change, or any other manual way to remove nutrients, then lights-out is fine since the nutrients don't make it to the scrubber.I would follow with a large water change, but I know you do not do that either.
My mistake... I meant GFO to remove P. Reading patents all day has got my head spinning.Typically GAC removes dissolved organics while leaking inorganic phosphates, while it is fresh and not constricted by a biofilm.
