    Hi Guys

    I received The Fishkeeper mags yesterday. I order a few of the back issues as well.

    I loved the Amano articles and when reading the specs of each tank I noticed that after lights out and for +-12hours on most of them he mentions he aerates the tanks.

    Now I know that most of us don't bother doing this and have our CO2's hooked up to timers etc. But I'm wondering whether aerating the tanks at night isn't in fact extremely beneficial? :scratch:

    What do you all think?

    i just started doing this in my big tank, apparently it is really helpful for the filter bacteria mostly.

    havent noticed a difference yet..

    Mmmm.... That is quite an interesting question you have Kryo....

    I will definitely be keeping this post open on my browser....

    I also do not know.... Well.... Plants do use oxygen at night for their night cycle....

    would like to know more....

    as far as I know most of us aerate our tanks after lights out and it's pretty much standard with running CO2..

    Really? Who else does it and can they please comment here?

    I used to aerate when I started out but then after reading posts on here that reflected a majority didn't aerate I stopped doing it cos the air pump drove me crazy in any case! LOL! But if the general consensus on this thread goes for aerate I'll definitely be hooking up the air pump and air bar again in the new tank.

    How do you add a poll? Mods can you help me with that?

    I aerate my tank after lights out. I was told many years back that its to stop build up of CO2 when the plants arent using it. Back then I accepted it. It became a habit and I have never stopped doing it even though I dont use CO2 in my tank.

    Ok now that my brain is buzzy from all this... I'm wondering if there is a relation to aerating and BBA.

    I have made notes on my tank since starting up (I know a bit OCD but it helps!) anyway, going back in my notes when I removed the air bar a few weeks later BBA showed up... :scratch:

    I also aerate my tank my CO2 goes of at 20h30 and then my air pump goes on at 21h00 and goes of at 06h00 the next morning.

    I aerate my "high-tech" tank. But, I don't have a solenoid valve on the CO[sub]2[/sub] yet. I left the air off for one night and the next morning my fishies were gasping for air and didn't look to healthy. Put the air back on and they are back to their happy selves almost immediately.

    The idea that plants "absorb" O[sub]2[/sub] during the night also compels me to keep the air on at night, even after I get my solenoid installed.

    Adding the oxygen to the tank at night is not really to help the plants. It's for your filter bacteria. Filter bacteria are all aerobic bacteria. This means they use Oxygen to go about their cleaning business.

    During the day, when you add CO2, the plants produce oxygen as a byproduct of photosynthesis. So your filter bacteria use the oxygen to do what they need to do.

    At night, when your plants start using oxygen and start producing CO2, there is no extra Oxygen source in the tank. So by adding an air stone, you're improving the Oxygen content in the water. In doing this, you're maintaining a healthy bacteria colony in your aquarium.

    We all know how quickly the filter bacteria die off when there is no water movement in the filter. This is due to the bacteria using all the available oxygen in the filter chamber, not because the filter is off and there is no water movement.

    apart from the aiding the bacteria, my fishies seem to enjoy the aerating as well..

    Makes sense Sean!

    My CO2 is on a time and I have pretty high flow in the tank at the moment due to heavy plant mass. But I doubt it oxygenates enough for the bacteria at night to recuperate from the few hours of low oxygen...

    Hhhmmmmm Ok cool!

    Guys do you think adding another Atomizer hooked up to an air pump on a timer will work? Or will the air pressure from the air pump blow the atomizer?

    I also aerate, nifty trick I saw from Morris so I copied and I believe it helps with better water quality, face it the healthier your filter is the better your water quality is going to be. :p

    An airpump will never build up enough pressure to force air through an atomizer. Just get an air stone. I see the Red Sea wood airstones are available locally now.

    I used to aerate when I was running DIY CO2 and when I first changed over but have not done so this year and have not noticed any ill effect. I maintain a very low livestock level with slightly over filtered system.
