din measure.... it is like around 30-32 i guess.
take note it is in the balcony.... it dont have direct sunlight- but is bright whole day round.
there is gradual algea built up on the glass- which i brush away.
some at the lava rock... mostly leave it there if not too severe
but the sand is gradually turning green if un-attended.

the pina tifida and java fern is doing alright there.
surpisingly Xmas moss also ok. ( i have another tank where it gradually turn brown.... it is with CO2!)
flame moss is gradually decaying and need to be removed.
Maybe at outdoor, even exposed to the heat, water temperature did not rise too much. I had a bucket with hydrilla & water lettuce, outdoor, it doesn't matter when, the water never feels warm. While indoor, water can easily go up above 30C when it is a hot day. I'm using fans now to keep water temperature from going over 30C. I get red algae on my plants, including java fern when temp spiked a couple of months ago.
That is why I like to use fine gravel than sand. Easier to vacuum & clean IMO. Did you use the turkey baster or similar when vacuuming? I use dropper, tied on the syphon tube. Very handy when vacuuming all the detritus trapped under the soil.
