Plumb the H20 flow (by using powerheads to and from?

I am so torn...I know it may be better to employ all the new school techniques, but I am afraid it will get too complicated and expensive for me. This tank is in my office, and I don't want to be obligated to come in on the weekends to service a very complicated system. Any advice would be appreciated!

Thank you for your time in advance.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
