I’ve been pondering if more light over fewer hours is different to less light over more hours from algae point of view. It seems like it would be reasonably easy to calculate how much longer you can keep lights on if you reduced intensity but I suspect it isn’t quite that straight forward. Any thoughts on this are appreciated.
As context, my angelfish are breeding and do look after their eggs well when lights are on. During light off period them or someone else eat eggs and I’d like to be able to leave the eggs with the parents at least until they hatch so have increased photoperiod. All my plants are undemanding but I do add EI-ferts and EasyCarbon daily. Majority of plants that survived for any length of time seems grow well. However I recently seen signs of Cyanobacteria, green algae both in filamentous form and dots on glass and relate this to extended photo period. I do appreciate that some of that may relate to bioload and flow patterns but it’s difficult to separate what comes from where.
