This setup is eight weeks old I have never seen ammonia, nitrite, or nitrate, at testable levels in this system. I have between the addition of the sump and water changes put 70 gal of new salt water in the system. I also started with good live rock and a culture from the live rock tanks at the LFS. I am going to wait and see if the system remains stable. Comments and Ideas welcome. I think i have improved skimmer performance by using surface box and locating skimmer intake in the overflow discharge compartment of sump
The float valve is from usplastics 1/4 id 3/8 od tubeing seems to work well, i have raised the float valve since the picture was taken.
