okay so now that i know i can use 1 heater, 1 diy co2
(on my planted 10) and use the 5 or another 10 as a sump, how can i build the overflow? i know i need 2 plastic boxes. and i need to do all this pvc
crap. i tried reading stuff from my searches, but i dont know where to get the "specimen box"
so you use 2 "specimen boxes" and cut some stuff out of the top of the one in the tank. you have a u tube, going into the 2nd box and have a hole at the bottom. you get some pvc
connectors and connect them to the hole and get the pvc
down to the sump. then you need to silicone come acrylic walls to make the place for the gravel, floss and stuff, then you get a pump and pump water back to the tanks.
am i missing something? can i get a premade box from like home depot or something? can i cut the acrylic with a hacksaw? etc etc.
