the larger the tank the less the paramiters change drasticly which helps the fish and plants from getting stressed other than water changes and trimming plants. i don't do much to the tank
How did you come up with the plans for this? I look at it over and over and I can't figure out how it all comes together. Is there a... well... to be rudimentary about it... a 'flower box' attatched to the tank? Or braced to the tank wall behind it? Did you terrace the plants in the aquarium? I imagine the filtration outflow is the head for the waterfall... or do they work separately of one another? What species of plants/fish did you put together? Soil? Lighting?
If you don't wanna go public with all this information, but would be kind enough to share with someone who's very curious about your methods... PM me? ^.^;;
