I am trying to figure out if I have a good flow rate for a 32 gal upflow filter that is built as so:
32gal rubbermade brute trash can That has a 2" dump at the center bottom. 8" settlement chamber at the bottom. 2" filter mat (scrubbie like matterial that is white that you can get at most the fish stores around here) cut to fit, put into layers the entire way up until about 8" from the top. 2" drain at the top for out flow that goes into a 9" wide water falls that dropes about 3-4". The water comes in via a 500gal @ 0 head pump that after everthing is said and done drops to about 350gal/Hour, is being pumped in to filter in 1" piping that goes down the center and tees and is shoot out of 2 90 elbow that create a cyclone action.
I had this filter working on a 100 gallon stock tank that I was using to quarintine 2 koi that were 5" long. I loaned it out to a friend that may or may not have killed off the good bacteria inside.
I now have it hooked up to a 150 gallon tank (built to a small scale of what I saw Jameskoi built in his basement, Thx Jameskoi). It has 10 new koi I bought (wrote about them in a different thread). I have been doing wholesale water changes (50percent or more) one to two times a day trying to keep the amonia under control.
It may be that the bacteria just has to re-estamblish and everything will be fine but it is also possible that the bacteria is still there and it just can't keep up. So, I am just asking if anyone else can tell me the optimal flow rate for such a filter or if I may need to add some more oxygen?
