We purchased a 300 gal rubbermaid stock tank and have a proposed filter system.
1000 gal Aqua Ultima II with a Pondmaster Hy-Drive 6000 .
1 1/2" plumbing from pump to filter and 7 l/ft of 2 " slotted drain pipe from http://www.conservationtechnology.com/
W/ gravel/ river stone over the slotted pipe.
Making water changes easier with backflushing and vacuuming weekly.
Our RES is about 8 " shell living in a 150 gal Rubbermaid stock tank.
Hoping to add one or two more turtles.
Basking , 100 watt solar glo, & zoo med ReptiSun UV
