Using evaporation resistant fliuds for use with aquarium heaters
    #4025723 - 04/07/05 12:38 PM (12 years, 3 months ago)

Anybody use any non-evaporative fliuds for use with aquarium heaters such as vegetable oil. You may have to add something to stop it going rancid, but it may be handy for TIT setups

Interesting, but I don't think you want anything except water in there.

I replace about a quart of water a month in mine, if that. The loss is minimal.

I agree with Diver. Also water has a high specific heat-capacity (basically, the amount of heat you have to add or subtract to cause a change in temperature), so it will stay at a more constant temperature despite environmental fluctuations.

According to this website, the specific heat capacity of water is approximately twice that of vegetable oil.

I used water myself with a container floating with substrate on it. I was thinking of the oil for the initial incubation more than for the actual flushing periods, or for long term low maintenance grows like sclerotia or invitro setups.
The heat capacity is not a big issue, oil has good heat transfer properties, it is just that water has really remarkable ones! Both act as good buffers and distributers of heat. We are only talking of maintaining a temp a few degrees above ambient which is easily sustained.

Another idea is just a thin layer of vegetable oil above the water. I am not certain that it prevents evaporation altogether but it definitely limits it.
