Temperature affects from outside skimmer line in hot environments

[DCR]

We seem to agree basically on the number, but not, perhaps, on the triviality.

I do not agree that my calculated 0.32 deg F temp boost is off, and your assertion that this small temp rise will cause increased heat release from the tank is true, but the uncorrected is close enough for a ball park calculation that involves big assumptions of tank volume and skimmer air.

You did not convert the watts to a tank heat, nor assume anything about tank volume. 3.5 watts for 24 h gives 84 watt hours.

That’s enough to boost 300 L of water by 0.24 deg C = 0.43 deg F.

Regardless of what we think is significant or not, folks can see the numbers and decide.

It is only enough to raise the tank temperature by 0.43 F in 24 hours if the heat removed from the tank does not change. The dissipation of heat from the tank will increase with increasing temperature and will mitigate this temperature rise significantly. Otherwise, it would heat the tank up to the outside temperature. Predicting the final equilibrium temperature where heat in equals heat out is a very challenging calculation. A 300 liter tank in your example will likely have a a couple hundred watts of energy already being directed at it in the form of pumps, power heads and light that must be dissipated. I don't think adding 3.5 watts is going to change the bulk temperature much. If someone asked if adding a 3.5 watt power head was going to overheat their 300 liter aquarium, I don't think anyone would say they should be concerned, yet the energy is about the same. That was the basis of my comment to the OP

I see no reason to turn it through any type of scrubber unless you have a local environmental concern (astoundingly close to airport or something similar).

Here in Miami, they do sometimes have trucks that drive down the streets late at night spraying insecticide on peoples yards. My air line would be to the back of the house. So it's less likely I would draw any of that in, but it is still a concern.

I am also somewhat concerned about smoke from my charcoal grill. The particulate sensor on my air purifier always goes nuts when I light the grill. I don't know if smoke would be harmful to my tank or if something like GAC would even help if it was.

I'd put GAC in the line in that pesticide scenario. GAC probably does very little for smoke, and that may not be an issue anyway unless there's a lot of it.

OK.

When I first moved to Houston from a small town in the Midwest, I freaked out the first time the mosquito truck was fogging the neighborhood. (For those of you out of the loop, the truck makes this loud buzzing noise and they do it at night)

I thought the zombie apocalypse was beginning.

I guess I'm going to find out. I unhooked the CO2 scrubber and ran an outside line through a GAC reactor to my skimmer.
