theory?: Temperate marine w/ temp. gradient in sand
I have been slowly working on making a temperate marine aquarium w/ species and creatures nearby ( in western washington area ) . And I just had a quick thought..
I read somewhere that when setting up a marine temperate system.. its often useful to crank up the temperature a little bit for the first week or two (again this is temperate, so it would usually be chilled/cold water), thus clearly 'cranking up' does not mean boil or anything close lol. The reasons for this recommendation were namely that this would help allow the live sand and live rock, and whatever else to establish themselves. (oh & this is done before any other creatures are intentionally added). After everything is established the water would be put back to a normal temperature.
but just a few moments ago I was reading something about reptiles and putting heating blanket under the cage to keep them warm...
AH HA! and so it hit me... what if a heating blanket was used under the tank?.. supposing my home-brew chiller does a good job, it should be possible to actually keep a slight temperature gradient in the sand on the bottom, while keeping the water temperature stable.
why would I want this: I would think maybe this would keep the live sand and its ''stuff'' more active, in a tank that I want to be as self sufficient as possible, with a thick layer of live sand, perhaps this would increase filtering capabilities. ?
so what are your thoughts ?
