Talking My 1st DIY CO2 (Some ?)

OK so I have an 8 gallon tank that's a little over a month old and I only have 6 vals in it (didn't plan on it being a planted tank) and 2 gups. The older leaves are starting to brown at the edges. I read a lot of the other posts here and so this is my "plan" so far...

A 1L bottle with the yeast mixture -> smaller bottle -> into tank -> ?

So...
1. I want to use the small bottle to catch any yeast... does it have to be filled with water or just empty?

2. Is this bottle size fine for an 8 gallon? (Tank will have more plants soon)

3. What would be the best way to diffuse the co2? I know that airstones aren't great but I can't go and build a reactor either

Thanks guys and sorry it's so long

I would replace the small bottle between your liter bottle and the tank with a check valve. You may want to use a 2L beverage bottle with 1 cup sugar, 1/4 tsp wine yeast, 1 tsp baking soda, 1 tsp soy flour or protien supplement. It should go at least 3 weeks. Fill with water 3/4 full. If you have chlorine in your water, add so dechlorinator.

Air stones will work but you will have to clean them often. I use a Hagan ladder.

If you don't dechlorinate the mixture water what will happen? I have been running the hagen unit for sevral weeks with a diy mixture but I didn't even consider dechlorinating the water.

The chlorine could kill the yeast.

So could I please have more details to flesh out your plan? For example how much CO2 needed depends on lighting, plants (are you planning for more than vals?), phase of the moon...

Well... right now I only have a 10w Biolux bulb over it (it's the highest they had for an 8 gallon and I'll get another one once this algae gets under control). I was thinking about some anacharis and still need to find something short for the front. Moon phase... umm... *peeks out window* a bit more than half... waning I believe. Does that really affect how much co2 they use? Hmm ya learn something new everyday...

Expect an new growth of algae whenever you increase your light. You need at least twice what you have now. That means you may need to remove you hood and make another hood or reflector that holds two 10W (or are they 13W) compact flourescent bulbs. When you get your light, then worry about the CO2.

Search the net for lighting articles and spend some time in the light section here.

Enjoy.
