excellent point. after reading this it occured to me that a terrarium situated on top of the aqarium would be a beautiful thing to see and control the evaporation. it would be a fully sealed unit, except at the bottom where water could evaporate through holes and provide moisture for the terrarium plants. the terrarium would have to sit on some kind of sliding, or motorized lifting shelf, so u could do aquarium work w/out having to manually lift the terrarium off. aqaurium lights would be in the terrarium at the bottom under a plant shelf.
as for the filtration system...i'd like to see a drainage pipe at the side of the aquarium[drilled glass]. this pipe would drain water into a smaller tank...much like a sump except fully sealed. the water would first be filtered through a sponge then drain into the main area filled w/ bioballs. an air pump would pump oxygen through a series of airstones running the length of the sump. the water would sit here for a day while the nitrifying bacteria would do there thing. then i'd pump the water to a long trough w/ a series of cartridge filters that could easily be removed and rinsed. we would lose some water here to evaporation but not much. the water would then drain into another sealed tank, full of plants that eat nitrifying bacteria. here it would sit for 2 or 3 days. lastly the water gets pumped to an r/o unit and then into a sealed resevoir where it can be topped off and whatever nutriens needed can be added. then pumped back to the aquarium through an inline UV. [good call eddie...i forgot about the uV]
so what do u think? i wish i could do CAD drawings so i could give a visual. i'm excited about this and would like to give it a try somewhere down the road. if any of u guys or gals see a problem somewhere, by all means give ur input! constructive critisism is always welcome.
