hey guys cheers for the helpful tips and for Eniram yes the window is closed for good what i'll do is you know how blinds can shoot light up or down yea? i'll be shooting it upwards hopefully decreasing the algae growth, and thanks for the tip i will remember to install the compressor when the cabin is good to go, for the people who are gonna bring the compressor i think its much more wise to install it and then put the tank up as well as put together makes more sense then putting the tank up then the compressor.
