Thanks Roger, I went back to 1-5-14 "Metal core on pump", which started to corroded after 12-1-13. Then 1-7-14 with a 95% water lose to the system...about 6 fish not eating very much (stress). First fish die on 1-31-14, the other 5 died within 3 weeks of the 1st one. My guess is they were the ones that got stressed out when the water went down. It just took that long before they died from starvation.

My "Vertigrow" setup is all made from PVC material except for the 4 x 4 end frame work it's wood painted with 100% acrylic. We haven't had any rain since I build it, so nothing could of been washed in to the system. Not much growing in the growth beds yet to cause any problem.

All the gold fish are still doing GREAT...they look like little body builders (all buff).

I'm attending a AP tour on Sunday and will have a chance to see and talk to a person in my area with a large AP System.
