My growth wasn't slimey just dark hair algae. I doubled up my lights now using 4 23w cfl 2700k bulbs. I also backed them up to 5" away. Also po4 went from .27 to .11 n two days since adding second set of bulbs. Should I reduce light from 18/6?

Screen looks a little brown today think I def need to turn lights down on time.
Looks green to me.
You could move the lights closer.
yea the green is the old left overs from cleaning it but in person you can see the newer growth is brown. today is when i moved my lights to 5" instead of 4" because i saw browning. should i just lower the time like to 12/12 and keep at 4" or leave at 5" and time at 18/6?
I would like to see some support on this concept. this issues keeps coming up (people with zero N and P not dropping) way too often for it to be explained away by their scrubber not being strong enough. Now I've noticed you posting in more than one thread that the ratio that is present in food doesn't matter.
since N has more than one export mechanism via LR / LS etc in addition to the scrubber and P does not, and P will not get absorbed (at least not nearly as efficiently or effectively) when N is zero or very low, then P will rise. I have experienced this as have dozen of others, in fact I am willing to bet that many scrubber users who have any kind of nuisance algae problem in their tank can attribute this problem to nitrate limitation. I just replaced my scrubber (T5HO) with an LED L2 so we'll see if that makes any difference.
I also don't see how the fish excrement has anything to do with it, since the new feeding-based screen sizing method is basically justified by saying that the only input to the system, besides FW top-off and dosing alk/cal/mag/etc is food, so the cycle that 'provides' nutrients to the scrubber starts with food, and ends when that food is broken down by multiple processes, fish excrement being only one of them, but still only an intermediary part of the process.
You gotta be right floyd, in nature A + B rarely equals C.
There are just too many variables, lots of which we don't even know exist.
Just google n/p assimilation assay ratio in reefbase or elsewhere.
Found this for anyone following along. Havent read it yet, but the first page makes it seem like what I am asking. Thank you SM
