Probably to stabilize the pH some. I don't think it is at all required, especially for Amazonian or West African fish.

Ter... that set-up would support what size tank? How long does the cocktail generate CO2? I looked into it once but with 700G of water running, thought it might be a big chore keeping them charged. Bill

Bill...to CO2 inject all your tanks it would be more economical to find a used regulator setup and either buy a 20 lb. tank or rent one. The bubble rates are not consistent with DIY CO2 generators and it would be a big burden for you to have keep replacing them weekly. You could use a manifold on one regulator and have a bubble counter for each tank to regulate flow.

I'm just testing it,the recipe should be good for two weeks and should work for up to 55 gallons (according to the forum). I have it on a 5 gallons right now.
I'm doing it more for fun because I don't have a huge setup of plants. I'm still a newbie to the hobby so I like to try new stuff.

I did this and it lasted about two weeks. It sure does help the plants but changing them out gets old! I just ran the air line into my hob intake and it dispersed the bubbles well. Never used Baking Soda.

Carbon filters remove chemical impurities(non-organic IIRC) from the water. They are great for removing medications and can be helpful if you suspect an issue with external contamination(in combo with a huge water change). However they get used up fairly quickly and don't really provide a ton of benefit in normal situations.

AngelAddict I'm using marine grade silicon to seal the tubes to the water caps. I put silicon on the bottom and on the top and is working good.
