Heating the substrate?

I have a little 10 gallon right now, and eventually will upgrade to a 25 gallon cube and move everything to that tank. I was wondering what people thought of heating the substrate? For some reason the idea popped into my head as I was looking at directions for setting up a seed starter for my veggie garden. Putting the seedlings over a heating pad improves their growth (apparently).

Would this same concept work with an aquarium? And how would I go about this idea? I was thinking maybe some waterproof heating cable zigzagged in the substrate. I don't want to get one of those reptile heating pads, because in my experience, they always end up dying and leave Miss Snakey cold, and it would be a pain to remove the pad from an aquarium (either under the glass or in the substrate).

I moss be in love

It's an old idea. First thunked up by Kasper Horst and Horst Kipper way back in 85 and detailed in their book The Optimum Aquarium http://www.amazon.com/Optimum-Aquari.../dp/3925916024

It's totally unnecessary. Rooted plants transport water in the substrate via their roots into their vascular tissues and out through their leaves. This process is known as guttation analogous to transpiration in terrestrial plants.

Nearby by a have a fresh body of water with submerged plants growing in it. One day to satisfy my curiosity I stuck my fingers into the substrate. Even though the water was shallow and the middle of July and the water warm the substrate was cold just a few inches down.

So save yourself some money.

There is no proof that the heated substrate is better than an unheated one. I have done both, and found that there wasn't a difference between the two. I also tried the reptile heater but found it hard to control the temp in the tank with the flux in room temperature.
In my opinion skip the cables.

If you cannot keep daphnia alive...I wouldn't even trust you with my pet rock!
