    I have the hydor green nrg diy co2 set, this comes with an electric diffuser. I hardly ever see many bubbles coming out of this except after ive changed the sugar, yeast etc each week. Because of this im considering changing my diffuser. Im looking at getting this one http://www.aquaessentials.co.uk/index.p ... cts_id=647
    does this need any electric motors etc or will the co2 from the diy canister just rise up the tubing from the tank cabinet into the tank and then through the diffuser?

    Also, in my bubble counter, the solution in there used to be clear and i could see the bubbles rising from the bottom to the top, now the solution has turned a milky colour and i cannot see anything, what is wrong here? Do i need a new bubble counter? As i cant go pressurised as its too much money, if i added a pop bottle (filled it with fermentation mixture), could i used air valve taps (im not sur eof their name) to connect 2 supplies to one line? Or do i need to buy something specialised to do this?

    Thanks

    Will

    Not seeing bubbles coming out of that diffuser means it is working as it should. It means that the bubbles are all disolving in the water before they reach the tank, which is a good thing.

    As to the cloudy bubble counter, it sounds like some of the yeast mixture has gotten into it. Be glad you had the counter there, else that would probably be in your tank. Just empty it out, give it a good rinse, and refill it with water.

    Yes you can use the air valves with DIY, although you might find you lose a little CO2 through these. I use one of these however, and find that with 2 x 2 litre bottles I lose very little pressure if any. I actually sometimes use mine to actually reduce bottle pressure when I have a new mix in one of them, I pull the cap off basically to release some of the gas into the air to help reduce how much makes it into the tank.

    oh well thats ok then :D

    do you think instead of making another fermentation set, adding easy life easy carbo would make my carbon levels more stable and stop having really bad algae?

    Thanks

    Possibly, you could also do both. Another option would be to go the pressurised route, I have just made the switch myself.
