Now one question and your suggestions.
As pump have original magnet that not keep pump tight from outside as acrylic is 1.5 cm thickness I planned to place magnet inside overflow side and place pump let's say 10 cm bellow water surface pushing water to other side of aquarium...
Did will suck too much also surface water that going to overflow or not even if I regulate openings on both sides of pump?
If will be too near surface create problem for overflow? Magnet is sealed well in any case will put glue around box lines if need.
Also comb level will be raised more with additional plastic to rise water level surface for skimming in box.
Dont want to place pump on oposite side of aquarium to avoid any ugly cabling inside tank ect. Only on side near wall and overflow hidden as per professional deformation
no visible cabling.
