CO2 best way

[Silly me]

Does anyone here use DIY CO2 system in there tanks and is it working?

I am not really having to much luck with my plants, I added some dupla pellets, and added lots of lights, about 3watts CF lights for every 5liters,

also I don’t have a UGF its a EHIEM something professional external filter, and lots of gravel of about 2-3mm in size, Most of the gravel I got from my dad discus tank that had lots and lots of plants the filter was also in the tank.

The only difference between my tank and my dads is the CO2 system, but is not the DIY with yeast, I don’t have money for one, so I'm looking at the DIY with the 2 soda bottles

Hi, I have a heavilty planted tank too and I acutally spent 35 bucks on a nutrafin CO2 system. I can probably help you out with the setup, chemicals and measurements (I'll just steal from the nutrafin measurements) if you want to e-mail or PM me.

I have done some research on "dutch aquariums" This is what I have found out. It may not all be accurate, so yall with planted aquariums feel free to correct me.

1. Many aquatic plants prefer soft, slightly acid 6.5 - 6.8ph water.
2. The substrate must not be packed too tight around the root cluster. If the fish are pulling the plants out, add one of those small metal bendy strips sold at LFS for anchoring aquarium plants. (I did this because my gourami kept yanking them out)
3. Trim the roots of new plants before planting them, plants take up nutrients through the tip of the root.
4. If any root tips are poking out of the substrate, gently push them back under.
5. Your light measurements are within spec. A 6500K bulb seems to work best.
6. If it's cold in your place, an aquarium/terrarium bottom heater helps keeps the roots warm (plants like having warm feet)
7. Fertilize sparingly with a balanced fertilizer (trace amounts of Maganese and Phosphorus)

Hope this helps

well i have a DIT co2 system but not with the cheesy yeast and soda botles i then to my DIY Specialist and got a CO2 canister and a regulator and hoked it up to a nutrafin CO2 System that i got pissed off with (yeast is more expensive in the long run and it ran into my tank so i scraped it).

i don't know if you have a shop that sells welding gases and stuff like that but if you do the system i have is the best low maintanance and there's no risk of the yeast going back into the tank.

the yeast system works fine but u got to be carefull of how full u have the sadoa bottles.

this link should help http/fish.orbust.net/carbondioxide.html

I have got a Haden CO2 system. It's basicly the same as the DIY one except the CO2 is released using a rising ramp system. You can actually watch the CO2 bubbles get smaller as they rise up it in the water. I suspect this is much more efficent than just putting it into an air stone.

Anyway the effictiveness of the CO2? Well I started adding liguid fertilizer at the same time and my plants went from limp excusses to heatly looking plants growing well in under a week so something worked.

Just for reference my water levels are currently:

GH PH NO2 O2 KH CO2
19 7.5 <0.3mg/l 5mg/l 14 23

Although I have upped my 02 level now (air stone) and C02 has dropped slightly as a result

A few questions:

1) How long have you been running your DIY setup?
2) How do you check production (tell how much CO2 it's making)?
3) How are you diffusing the gas, and is it the same way as your dad does?
4) What's your tank size, and how many bottles are you running simultaneously?
5) What is your CO2 concentration 'naturally', and with your DIY setup running?

Hi, I have had a small drop of yeast mixture go back into the tank - Yes I had no safety feature to stop it; I am foolish

My question: The water is slightly cloudly, I have added 'filter aid', the fish seem fine. Has anyone else had this happen ? If so what did you do ?

TIA

Hi,

Rather than creating a new thread i thought i'd ask my question here...

I set up a new small tank for mainly plants and have about 1.8W per gallon. The tank only has a water dept of 10-12 inches so it could be considered 2W plus maybe. I have a small Powerglow tube light it. Anyway i decided to create a DIY CO2 system and bought a second hand bubble counter... I got a 1 liter bottle and filled it with about 2 inches worth in depth with sugar and then added half a tsp of dried active yeast which becomes active again in water. CO2 started really well but it stopped after a few hours? I've started a second go since and made sure i dont have any leaks which i dont! i used extra silcone on top of the old to be sure! Any ideas why the CO2 stopped? As i said i've got a new solution on the go now so i'll let ya all know how this goes/went.

cheers

I set up a DIY Yeast CO2 generator. Cost me about $5 or so to do it. I beleive the yeast was a $5 investment as well but i bought a large jar of it and it's lasted me 3 months so far.

I used a gas separator setup to keep yeast of of the tank. If setup right, it's pretty safe.

I have the 2 liter bottle that i fill 3/4 of the way up with sugar/water/yeast. From there one silicone line runs into a small Poland springs type bottle half filled with normal water. The line runs under the water level so pure gas goes into the water and rises to the top where another line comes out of the top and goes to the tank. I have a fitting on my filter inlet so the gas gets drawn into the filter impellar and disappated. I'm trying to find a place that sells the Hagen C02 ladder so i can use that but my method works.

thanks for the link trop junky I will try making this set up myself...i like it
