    So my current DIY mixture consists of:

    *1/4 tsp yeast
    *1/4 tsp baking soda
    *2 cups sugar

    This lasts me about 8-9 days maximum, so now that I got my DIY setup is settled and working fine without any issues I am going to start experimenting with different mixes. I have read up on the life cycle of yeast and the reason why yeast dies after a set amount of time is due to the alcohol levels reaching levels that kill the yeast.

    So when my current mixture has run out I am going to instead of just normal white sugar use a mixture of 1 cup brown and 1 cup white. And instead of normal yeast I will be using brewers yeast. The reason behind this is that brewers yeast is far more tolerant of high levels of alcohol so in theory my mixtures would then last longer.

    After that I will move onto wine yeast and see what kind of results I get with that ideally I am looking at extending my range to between 2-3 weeks for my DIY CO2 mixtures.

    I got my mixtures and amount of water just perfect. My last mixture lasted me over 4 and a half weeks which is really impressive. So my setup will set me back around R 50 a month which ain't too bad.

    I'm also looking into DIY CO2 and I read somewhere that some people in the overseas use gelatine (jelly) to extend the live. Some go for over 2 months.

    I'll try to find the link and post a bit later.

    Just for interest sake. Pressurized works out cheaper in the long run. To refill a 2kg tank costs R25 and on my tank which is 324L currently 1 tank lasts me over 2 and half months. I understand the initial outlay for pressurized is expensive but in the long run it is much less hassle and cheaper to maintain. You can buy regs with Solenoids for very reasonable off eBay these days even with the R/$ exchange.

    The initial outlay cost is what scares me off, because it would basically cost me the entire cost of my current tank setup just to go proper CO2. And even then I would like to keep my tank tank low tech as possible, and the type of plants I currently have in my tank are low maintenance so I cannot really justify that amount of money on it.

    As for hassle not that much for me, remove bottle chuck out old mixture make new one attach and leave.

    In the the long terms almost everybody goes over to press CO2 rather than DIY which is unstable and a hassle, not sure folk have tried in a pond though ?
