I don't use the photocell for 2 reasons. First, aquaria tend to have lower oxygen levels at night due to lack of photosynthesis so I want to keep the flow going to improve O2 exchange. Second, when I have the Streams periodically stopping I find that they are more likely to not start again than the likelihood that they will just stop on their own.
That latter reason is also why I quit using the waveboxes on a tidal schedule- they would sometimes not start again and then need premature cleaning to get them going (like after only 1 month).
