When to add CO2

1317 Views 13 Replies 6 Participants Last post by  zzrguy
Well I've been cycling the tank and the numders are coming around.

So when should I add the CO2?

I have the Nutra-Fin DIY setup I also have a UP Aquatic defuser.

Should I just use the defuser that come with it.

I'm not an expert, but I think The PTP will need a litlle more info.
Like, what type of lighting, ferts, plants, and size of tank?

Sorry
Its a 29gal it has a about 48 watts of light for 12 hours.
The fert is still be work out and the plants are still being added. Right now it has Root-Tabs and dosex with Flourish Comprehensive once a week.
I'm not entirely sure which diffuser this is, but generally speaking, the DIY kits don't build up enough pressure to use a conventional diffuser, so you'll likely have to use the ladder.

I used the same system in my 29 gallon and the results were negligible and I moved to pressurized. If you can, see if you can get a better yeast or a bigger DIY setup.
I have diy co2 on my 29 gallon (2-2liter reactors). I use a maxi-jet 400 with a gravel cleaner on the output as my diffuser. The bottom half is filled with sponge with aprox. 4 inches of open space at the top of the tube. I prefer to run my co2 into the intake of the powerhead, however its a little noisy. The co2 is diffused to the point you can barely see it. My drop checker which is in opposite corner of the tank stays lime green 24/7.
well im going to add the CO2 today in hopes it will curbs any algae blooms.

I have exactly the same lighting and tank size as you. 12 hours sounds like a bit too much since at 8 hours with ferts and co2 I still get brush algae. See if you can catch up on the ferting. You will need the plants to out-compete the algae
plants don't out compete algae
healthy plants defend the system

Do you mind expanding on this? I think I understand, but I want to make sure I'm not missing something important here that would benefit me (and possibly others).

Thanks!

Plants are a major complex organism and require more nutrients to survive than algae. For instance u can test for zero phosphates and nitrates in water on ur test kit and have very unhealthy plants yet a tank full of algae which is a simple organism and can survive on very small untraceable amounts of nutrients. It would be impossible for plants to outcompete algae. Algae would win

Instead healthy growing plants will defent their territory.. it takes more than one. Usually a biomoss that fills about 50% of the tank or more is sufficient for plants to defend the system. However they still have to be healthy and growing well!
Its hooked up and I quess running. no bubbles yet but Im guessing it needs ti ferment for a while.
Well still no bubbles but it seems to be move down the line its pushing the water down the line more and more.
most DIY will produce bubbles in about 4 hours
it helps to dechlorinate or boil ur water
add it to the mix when its about 85 degrees
Dam did not dechlorinate. Bubbles are almost there.
