Would adding an 1/8th of a teaspoon of sugar or so to a 10 gallon tank suffice for adding carbon?

Adding excel seems to have killed the anarcharis.

Bottles of yeast / water / sugar etc. in my house would probably end up all over the dog, the kids, the walls etc.

No, no sugar.

Anacharis is very sensitive to Excel. Don't add it close to the anacharis and maybe less than the recommended dose next time.

I echo the "no" to the idea of using sugar as a carbon source. Don't even think of it.

In a NPT the carbon is supplied by the atmosphere plus the natural decomposition that takes place in the soil substrate. It is not necessary to add it in another form.

Good luck.

Bill is right. Sugar is like adding gasoline to a slow-burning fire.

I added sugar to one tank about 20 years ago, and it killed a couple fish that night.

Just add more fish and/or snails and fishfood to the tank. Fishfood and soil organic matter releases carbon dioxide (and other plant nutrients) slowly and safely into the tank (my book, pp 78-82).

So sugar DOES release carbon in the aquarium?!? In the form of CO2, or straight up carbon?

I'm not saying I'm going to run over and chunk some in my tank, but I'm suddenly very interested in how this works. PLEASE do tell!!!! :hungry:
