Lovely Aquascaping room John
I use these lights on my 53cm tall tanks, and always run full on, with no visible algaeThe setups are using Kessil 160's that are dialed down

Don’t forget that when you decrease the intensity on these lights (while the driver tech maintains spectra) the “cone” of lightfall diminishes significantly
Scaperoom is astounding
Beautiful studio!! My hunch is lighting.. your tanks appear to be sparse in plants, heavy on the hard scape and that’s your style. I would back way back off the lights some, Crank up co2, or add more plants. This style is a tough one to balance. My 2 cents
Have a look at the below link...interesting!
While possible, this seems unlikely - does your pH drop to 4?Similarly thou, lack of bacteria due to lower ph and ammonia/cycling happening on a weekly basis could be a thing.
There’s a lot of meandering on forums where conclusions (cause/effect) are drawn regarding various parameters
I run my tanks at my tap water parameters, KH, GH very low (it’s basically rain water/snow melt that collects in a ground reservoir (and can get a bit peat stained during storms)) pH 6ish, 22-26C, adding Tropica fertilizers - except when I don’t - and using Tropica soils the last while
(nutrient enriched base layers such as Sera Flore Depot beneath fine gravels previously)
I tend to keep fish from very soft water areas so I don’t add KH and GH, I add low to moderate CO2 (again depending upon fish comfort)
I often have significant ambient light and even direct (morning) sunlight on tanks - fish are meant for sunlight viewing
Tanks run with minimal algae, occasional diatoms during startup (I’m surprised when it happens, despite fluctuating CO2 (especially when I run out and don’t replace for a few days ), rather erratic care (my intentions are good) ...
Recently I’ve let my kitchen nano run wild: CO2 ran out early December, no fertilizers, water’s only been topped up since, some plants have receded and disappeared (the Eriocaulan ‘polaris’), others have become a jungle, photoperiod has not changed as that is programmed into the light - it’s been an interesting experiment in neglect - and still, no visible algae
(Note there’s a few snails and odd shrimp I still occasionally see)

The science of aquarium nitrogen cycle has changed significantly in recent years, Darrel has provided some decent links (just the first post in that thread is pretty convincing )
Most dehumidifier water does not test well - I don’t know where/how this methodology developedI did spend a bit of time changing the water in one tank with water from my dehumidifer and I have to say things were the same if not worse in that tank for that period.
