I have a 29L tank which is heavily planted and has the following occupants:
5 3-4" Giant Danios
3 3-4" Clown Loaches
4 1.5" Tiger Barbs
3 2" Otocinulus
4 or 5 Cory cats (I never see them any more b/c of the plants)
4 2" Zebra Danios
2 2.5" Mollies
3 1.5" Thai Foxes
1 4" Gold Gouramie (the godfather of the tank)
(which comes to about 73" inches of fish)
For filtration I have a Whisper "2" power filter (listed for 10-20 gal.) w/
only floss (this filter is used for purely mechanical filtration) and a
Marineland Biowheel 30 powered by a powerhead with a sponge prefilter.
The tank has not shown any measurable levels of NH4 in months. I have been
told that plants prefer ammonia over nitrate. If this is the case then
would it be better for me to not use the biowheel (since it converts all the
ammonia to nitrate) and just rely on the plants to take care of the ammonia?
I was just wondering... What are peoples thoughts on this?
