Hi everyone, I've read alot on this forum for the past 2 moths and I've been tempted to try DIY Co2 with Yeast in my new 25 gal.

But first a bit on me.
I just started in aquariophilia and my thank has been setup for 4 months. I got 24 fish and a couple of plants.

for a couple of days now, I've notice some staghorn algea, so as I've read I OD excel for a period of a week. without much effect. At my LFS, the guy suggested to start injecting co2. Not having the money to go with compression I decided to give a try to the DIY method.

I've used the method described here. From the sticky

with this recipe:
Setup in the experimental planted tank. 9 gal.



After more than 6 hours, I am guetting a bubble per half an hour. I already checked for leaks everything seems air tight.

Also my tap water got a ph of 7.8. Is this a problem?

Does my air line is too long?

thanks alot
