What’s the shortest photoperiod I can have for chaeto to survive? I’ve got an ALR1 and a 20 gallon tank. I haven’t started using it yet, but am aware it may well decrease my NO3 and PO4 too much. So was thinking of only using it for about 20 minutes a day. Is that too short a photo period for the algae to survive? And can I light the algae without running water through the reactor?
Thanks in advance for any help.
