DIY Co2

Overnight when the temperature drops the co2 stops working. So i just gave the bottle a shake and away it goes. Like biffster says the co2 has to be in a warm room to work efficiently. I'll be keeping an eye on it to see if it makes an impact on the plants as 1 or 2 vallis plants don't look to go at the moment.

ado have you checked your pH lately i did mine
today its gone from 7.6 to 6.6 in two days
so yes the answer is co2 does lower pH rather
quickly i have a feeling it as some effect on the
nitrate as it seems to be lower than what it was
the last time we tested it strange think i will have to
look in to this more closely please tell me your
findings and i will post mine as well

Yes I did check but did not have a drop as drastic as that. Mine was around 7.2 from 7.8.
It might be because of the volume of yeast you are using as the more yeast the faster it will riact to the sugar. You could have too much Co2.
I only use 1/2 a tsp. I would probably get about 5-6 bottles worth of yeast from one sachet. Ecerything I have read recomends to use between 1/4 and 1/2 tsp.

its turned right down to a very fine
stream of bubbles i have put a clamp on it
to slow it down i have done it from the start

I think if you reduce the yeast to 1/2 tsp then you won't have a need to use the clamp.

we have low carbon hardness over this
area if you leave water to stand for a
week it will drop to under 6 in a week
so i am not going to let it worry me i
find a piece of tuffa rock or some cockle
shell

youll find when it first starts it puts out quite a bit of co2 but then it settles down to a steady tricle

cheers mick thats what it is doing

Andy i have a box with some coral shell if that would help sort levels out

i sounds good smoggs i will ring you on monday
to see about coming to pick it up if thats ok with you

yeah no problem mate, its crushed as i had some running through filter

cheers smoggy

The vallis is starting to look a lot less yellow and more green now. What a difference the co2 does. I'm quite impressed.

That's good to hear! I think I'm going to have to trim some of my plants very shortly and have a rearrange they are growing that much!
