Hey you guys =] hows it been...well right now im in the middle of planning out the structure of the pond....the thing is....how would I heat this whole pond ? Atleast to 76-78 degrees.....Also the plan on the dimension is a 12'x5'x4'....and this is going to be an above ground pond with 2 plexiglass in the front for viewing.How thick should i go as for pressure within a 4' high pond with that kind of lenght......? The price is not a problem no more....before i had a problem in having the money to only by the fish but not the home....but now i have the money to use to support the pond with the equipment! My whole family is in the idea and will all put in money to pay for the water and electricity so yea as that now is out of the way lets get back to the discussion of the pond.What large plants can go in the pond to help with filtration and also not get distroyed by my current fishes in my fish list....? By plants i mean like those roots in the water and the actual plan t above the water line.There was a video on youtube with someones aquatic santuary for rescued silver arowanas,pacus,catfish,a single piranha,and i think a trimac or and a devil....Those roots in the vid are like what im looking at getting to add to the sides of the pond...
