Is it true that when there is a foam fractionator, there's no need to think about the UV light suppressing plankton? The foam fractionator will eliminate plankton anyway, with or without UV. And without a foam fractionator, it's difficult.

It is correctly noted. Unfortunately, not everyone understands this... Moreover, the loss of plankton due to UV and skimmers will always be compensated by feeding the corals, especially since almost all corals, except for non-photosynthetic ones, provide for themselves quite well through zooxanthellae. So the fear that UV will deplete the aquarium of microorganisms to the point that life in it will come to a standstill is nonsense. There are so many microorganisms in live rock and sand that even with the most powerful UV, the aquarium is not at risk...

I reduced the overall flow rate in the aquarium to about 900 L/h, accordingly the flow through the UV, since it is installed in-line with the feed pump, and the water temperature increased by +1°C to +26°C over 12 hours, which is a fact.

+26 is quite normal. Even +27°C is too.

Did you notice that the outdoor temperature has risen from +15 to +25 during the day over the past 24 hours? And it has been increasing every day before that as well. The temperature in the apartment (house) has surely risen too. It's not noticeable for the body, but it's visible on the thermometer.

For my house, a fluctuation of +21.5-22°C is not acceptable; this is a specific temperature maintained by the thermostat in the house (individual heating) - when the temperature inside rises to +25°C, the air conditioner will turn on and maintain +23°C.
