I am getting back in the hobby. Previously I had a 8' x 2' x 2' with a Flower and a BD. I had to sell off everything including the tank. Now I am getting a 10' x 4' x 2' and needed some advice on where to drill holes for my filtration. Ideally I would like to set up a reactor. I know this could just be personal preference but I appreciate any suggestions.
Thank you!
Thank you!
