my 8 inch draw tubes, are fool proof draw of 8 inch's of art out of each tank, at maximum... today I modified my gravel vacuum to hook to my draw pump, so I can draw that water from the substrate if desired... also this set up would be used if Zi anted to drain the tank completely...
the only issue I've had, is my foot sometimes bumps the pump out pump, and the cheesy barb fitting attachments, strip off the threads on the pump, because of poor manufacturing tolerances... I've checked the threads on the pump, and they are 1/2 inch NPT, so I'll replace those with brass fittings, with teflon tape on the threads... I'm not worrying about any leaching, as this is all on the waste water side, 10 feet of drain hose away from the aquariums, so shrimp will be safe with this set up... I'm really liking my Indy pit crew fast water changes, at the push of a button... now there are 2 tanks, I'd really like to clean the substrate well
