Overflow Box Help

[Dreamsofpeace54]

Need help finding an overflow box that will allow me to keep my water level low for my bichirs/gar. My tank is not drilled and no i will not DIY (these end bad for me).

Any suggestions. Tank is 75 gallons

How low are you trying to keep it?
Do you have a glass canopy?

 

[Dreamsofpeace54]

yes i have glass canopy. Without it id have polys and gar all over the floor.

i like to keep it pretty low 2 to 2.5" below the black trim on the tank.
it doesn't have to be THIS low, but i think id prefer at least an inch.

Which ones have you looked at? I know my Eshopps on my reef is adjustable, probably an inch below the trim.

If the glass canopy and the plastic strip along the back are tight fitting it shouldn't be much of an issue.

What size tank is this?
What filtration is on there now?
What filtration are you doing with the sump?

75 gallon tank 48"x18"x21"(tall)

is has a saltwater filter on it now, black box that stays intank. Reefflo i believe its called. got it a long time ago. pump works great but no room for media.

6 clownloach, 9 polys, a big green terror and the gar produce alot of waste so im trying to make up for it.

i wanted to make it a 29 gallon with the maze or whatever of biomedia. would run the output from the overflow through a filter sock.
