Tropical freshwater aquarium with lights off
Aquarium in the evening – 28-Oct-2020

We put the clocks back to British Standard Time last weekend, but I haven’t yet reset the timers on the lighting and CO2 for the aquarium.  I have been limiting the time on for the lights to 6 hours per day to combat green spot algae which means it’s tricky to actually get to see the aquarium lit up – it’s still off when I leave for work in the morning and often is back off again by time I get home afterwards.  I’m going to see how much work it is to reset these timers.  If I can ever get the algae under control, I’ll try increasing the lights-on period to 8 hours per day which would also help.

It does look like the algae is starting to clear up a bit…
