Well, I seem to be over the little spike of nitrites and ammonia after adding 40 pounds of LR
(replacing the bio-balls with LR
In the last couple of days, though, I've had this odd burst of brownish algae mostly in the front of the tank and particularly on the substrate. I do see it in other places, though...
It seems to be heaviest in the front nearest where the newest rock has been sitting for the last week.
Am I looking at diatoms or something else? How do I deal with it? It doesn't seem to just "blow" off easily - but if I pick up a piece of the substrate and rub it with my thumb it definitely comes out.
Any input would be appreciated.
Yes, I have added some new lights and they might have been running a bit more the last few days than they would normally... but I'm trying to get that back on a good schedule.
