    Hi all,
    Great site, i have trawled through it for some time and what a volume of tremendous knowledge. i love enthusiast forums people are so willing to share. Unfortunately I have much more to learn than to share

    I have had aquariums for 30 years until 7 years ago when due to circumstances i have been without.
    i have just aquired a 4 ft x 2ft x 2ft ex marine tank with a sump type bio filter and a moozoo halide fitting with twin 150 w and moon flouros.

    i plan to have a well planted aquarium as the ones i have loved the most have been the wonderful environments created in tropical planted aquariums.

    I have purchaced substrate additives laterite and flourite which i plan to blend with some fine gravel. i have also purchaced a co2 reg and diffuser etc.

    My question is as i believe these filters are gass exchange filters how draining will the sump/ bio filter be on the co2 , should i look at other filtration? and if so what are the recomendations?

    If i can maintain the sump should i also include activated carbon (within the sump and or should i purchace an internal filter for this and other purposes.

    Due to my buget I will most probably start with the existing filter setup and make changes as funds are availabe.

    Thanks in anticipation Mitchell

    What type of c02 reg/setup do you have?

    You will need a drop checker (DC) that contains a 4 kh water solution that you can use to ESTIMATE the ppm of c02 in the water.

    You can use these. Many of us have overflows and sumps/ wet/drys. You can seal the sump with duct tape or whatever, and then look at your overflows, as this is where a lot of degassing occurs. The less waterfall the better.

    Many place carbon or zeolite or whatever they need in a sump. A sump can be very useful. You can add other filtration if desired.

    Please read around the site and try some searches. I know recently I posted several links to good threads around c02, drop checkers, etc.

    Also, think about current and flow as this is also vital.

    Looks like you have a 120 gal tank? and 300 watts of light is a lot. That will cause high nutrient and c02 demand, so think about this more.....

    You may want to lose the actinics and switch to a 10k or 6500k bulb......

    Good luck.

    Hope this helps a bit.
