Well skynoch here you go

I didnt bother with the silicon and the bulkheads.... I never have before and i havent had one fail yet, the seep in the pump is still there even after the teflon and pipe dope so i have to chalk that up to bad threads on the pump (there rough) so im going to try the magic tape or a new pump...
I have 2 ball valves turned way down on the 1/4 inch line on my drip system so i figured a psi regulator wouldnt be needed but a 1gph nipple is running at 2.5 so ill have to invest in one i guess regardless.
Had an amonia spike in the 180 today due to me stealing sand and bio from it for the 300 and decided in damnd if i do and damnd if i dont...... Stressful fight bagging em but only 2 dropped scales and a few jumper silvers (in bags)

Everyone is happy now and the auto changer seems to be doing the job after testing the out water at 40 gallons a day....
Thanks again for all the help guys..... Probably would still be messing with the 180 had i not found this forum and all the AMAZING info
