OK, the tank I'm leaning towards has a built-in overflow box (it was used for saltwater previously). Like I said before, total noob here - so I need to clarify some things I'm not exactly sure about at this point...
I realize there are holes drilled in the back of the tank where the overflow is...and these are fitted with 'bulkheads'....so ones is used to take water out and one is used to put water in...but....
How does the dirty water get into the overflow box??? Turtle poop sinks. *looks dazed and confused and part of that may be sleep deprivation*
If I use a canister filter, or pond filter, either one, I realize I have to have the pipes or tubes to lead from the bulkhead fittings to the actual filter - do you have to have a water pump to force the water into a canister filter or does it do that on it's own?
Am I even making any sense at this point - I don't know! I'm lost in all the choices : O Help me please!
