i have a question about where i want to put my aquarium. right now my 180 is up against a wall in my dining room that is about 7 feet long. im wanting to upgrade to a tank that is atleast 8 feet long and the only spacein my house this tank will fit is up against another wall in my dining room, but the problem is there is a window on this wall. is this going to be a problem? i never open the window and the seal in the window is fine and i have wood blinds i keep down all the time. and another question i have since im on here is when i go to setup my new tank and i put my gravel from my old tank into my new tank and fill it up, will it be alright for fish right away or will i need to let it cycle. im not sure bc i know the gravel has bacteria and all that good stuff but im switching from canister filters to a sump. so i just want to make sure i have all my ducks in a row before makeing this big move. im wanting to bulid a 8' X 3' X 2, do you think this will be big enough for a male motoro and maybe a hystix in the future. like always any help is appreciated.
