DIY CO2 System for planted 200L Aquarium

I'm looking at making a DIY co2 system for my 200l aquarium. buying one for this size tank will cost about £300 (too pricey)

I pretty much know how but the problem i got is how much yeast/sugar/bi-carb/water mixture do i use for this size tank?

Can anyone help tips advice has anyone ever made one of these?

Thanks in advance

Chris

there is a post about it in plants
i have a home made co2 system
up and running now i use two cups
or large handfuls of sugar to 1 ltr
of boiled cooled water mix together
sugar and water till its totally dissolved
then leave to stand for 24 hrs before adding
yeast i just use a good bread yeast shake and leave
to stand for four or five hrs after this time the mix will
foam up it is now making co2 gas i leave out the baking soda as salt kills off yeast as i have just found
out a few days ago from a master bread maker my
mum lol

keep an eye on your pH as co2 lowers your pH
very quickly

Cheers mate so that mix would be ok for a 200 L aquarium?

Im looking to lower my ph a little anyway so that shouldn't be a problem.

The plants are starting to look better with the co2 and there are signs of multiplying.

this is a home made co2 reactor and system
is made remember to remix suger water yeast
mix as soon as the bubbles start to reduce

Il try get few pics up of mine on fri aswell biff

thats one i have just set away to night
that mrG i have three systems running now
two home made and one shop bought disposable
one

Ive got two bottles running on my one tank because of the size

i have one bottle on a four foot tank
an the plants are loving it and the one i have just set away is on the just set away 30 inch

Actually this is on a 200 litre isnt it is 1 bottle showing good results

Ar well thats good how much yeast you use bif and sugar

The pop bottle has a ridge near the base. I put the sugar up to the ridge and i topped the bottle with warm water up to a ridge half way up the bottle. The sugar has to be dissolved. So just swish the bottle around till the sugars gone. If the waters too warm, wait till it cools to lukewarm or blood temperature before you put the yeast in as the hot water kills the enzymes in the yeast and it wont ferment.
Add a packet of yeast to the water, swill it round till it mixes and wha laa the mixture is ready.

I use a teaspoon for the yeast I dont use the packets. How many bubles per second do you get

1 per second or there abouts

Ok biff cheers

i am also defusing it using a
fluval 3 plus instead of the normal
way

My cig filter trick is doing well so far. Also when the co2 reachs the top is where the out put of my filter is so the bubbles get pushed against the glass then back down then eventually get to the top of water slowley. So. The bubbles are in double as long to give better co2

the longer the contact with the
water the better

Yeah I know thats why ive set it out like that so stays in longer

i like the idea of a bubble ladder
but dont know how to make one
i would by one but dont know were
to

Ano. I was looking on ebay etc cudnt find any. There was one from abroad on amazon but im guessing if they ship here will be expensive

i guessed that :rotfl:
