Okay so the tank is just too loud and needs to be fixed. How far under the water can I run the drain line? Will be using flex pvc. Also coming off the gate valve mod on my ASM can I run that return under water as well? Thanks!!
i reccomend puting the drain about 1 to 2" under the top of the aquarium, sounds like your having a problem with your durso standpipe rather than placement of the drain.
