And DT have no flow or water exchange through filtration? The flow in the sump is much less then the DT right?
10-12"
Yes they do, which is why a heat source of any kind and anywhere in the system will heat the whole system not one section of it alone. That's why I pointed out your sump has flow and can't be used to prove that LEDs do not add heat to water.
I'm a huge fan of Tunze but they can be pricey. I'm not up to date on ATO systems because I've gravity fed my systems for the last 6-7 years. That's hard to do in a nano though.
I run radion lights also. My tank goes 77 to 77.2 all day and all night consistently. You're right there is no debate on led lights their impact on tank temp if mounted properly is negligible. Now lots of other factors play a role like humidity, window light, house temp, heater quality, glass lid, etc... but lights are not a direct factor in tank temp changes.
Additionally you contradicted yourself by stating the flow in my sump fuge negates the affect of my 12 hour light on it because you state your fuge which also has flow is the source of your temp variations.
We will agree to disagree there I guess as. I feel mine were mounted properly, in a climate controlled house, a rimless peninsula in the center of my living room, eheim jager heaters controlled by apex? Dead of winter, fans would still kick on. I had ventilation fans cut into my stand as well to remove equipment hot air. Still temps would increase alongside my photoperiod. But, maybe not for some.
No I told you your sump has flow? SO stating that that section would be hotter than the rest was an incorrect assumption.
But I never specifically said that section was hotter because it isn't. That's where my temp probe is and I was pointing out that the temp never changes there even with the light on. You said that is due to flow and then you said your fuge is the source of your temp variations due to the light and cover yet of course you have flow like me.
I think it's more related to his glass cover retaining heat though but I'm a big fan of the Helio heating elements and controller for maintaining my temp so well.I see, your overall temp never changes. I read that as that section doesn't get warmer.
No issue with a little debate here
I just wanted to make it clear to the OP that LEDs can indeed increase water temperature since that was his question.

Kessil has a nice small footprint for a nano tank.
I have two biorbs, both with led lights. The lights are attached to the lids and both lids get very warm. I don't understand why these two led lights are the only leds I've ever experienced that got warm. This should not happen because leds DON'T get warm. It's one of the best things about led lights. It definitely has left me very concerned!!!
I disagree with you. When I turn lights off, the temp hangs around 80. I turn them on daylight setting, the temp rises to 85 in about 2 hours.
An old thread but it's ok to disagree. My radion lights run at 100% intensity 8 inches above the water for 10 hours and has no effect on my tank temp. Take a look at my fuge light running for 12 hours overnight right on the water surface and my temp probe is in the fuge also and still the LED light has no noticeable effect on my tank temp.
