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
