Aquarium Advice FINatic
I just bought a ball of chaeto and tossed it in my sump, started reading online about lighting cycles (which from what I gather, it's good to run the sump lights opposite the DT lights..?) and came across it messing with ph.. Has anyone had experience with ph swings from adding chaeto? I saw one comment that the reason for running the light opposite is to help control these swings. Any help here is much appreciated.
