The bolbitis still hates me [emoji4]
I ran an experiment for a couple of weeks (ie I forgot I’d done it), where left the second light running. Result was drastically browned off bolbitis (which I’ve generally taken as deficient in majors not algae growth) and green algae on tank glass.
Nitrates read 5pmm so upping dosing. Out of date phosphate test kit read 0.25ppm and new kit read 1ppm (I thought interesting that I’d found out of date nitrate kits to also under-read).
I’m still tempted to run the second light for an hour just as it sits there lol but apart from one plant, the ferns and Anubias I confess seem fine without it.
