No im just running FW
through the system to clean it a little and so i can get a stockman standpipe installed into the overflow, hence the water change to get some of the dirt out of the water.

i'm surprised that a 120gph pump will push water that high and still be strong enough to notice it. are you sure about that? btw, if this is in fact a 120gph pump, which i doubt highly, your HOB
overflow is in danger of losing siphon. the smallest HOB
overflow i know of is 300 gph
. you should be pushing it to it's limit in order for it to function properly. i'm assuming this is a HOb, because in pic 1 i see a J tube. but looking at the overflow with the bio balls in it, i'm confused.
Its an internal overflow and it has a 1.5" hole in the bottom of the tank that drains into the sump, the guy who i bought it from put the bio balls into the overflow to stop the sound of water rusning through the system, really it didnt work IMO
so im making a stockman standpipe to fit in there instead.
If that makes sense...
edit: pump is a rio 1100 so rated at 300gph
