As part of my rebuild, I had plumbed a line out to my "fish closet" out in the garage which is about 12-15 ft away. That is where I've had my mixing station. The intent was to have my reactors setup out there rather than under the tank to minimize water splashing in the house and make it easier to swap out media. Anyway, I run a biopellet reactor which requires a lot of flow to keep the pellets tumbling. But, I couldn't get enough flow to make them tumble. Sure, enough, I have not been able to get my NO3 below 25ppm. My GFO reactor requires a lot less flow and PO4 have been staying below 0.04ppm. So, I completely under estimated how much friction loss I was going to have pumping water from one of my return pumps (Vectra L1) out to the closet. I ran 1" PVC... It would have helped if I had run 1 1/4" or even 1 1/2"....ah well.
So, I replumbed my biopellet reactor so that I could run it under the DT in the sump. The output is now going directly to feed my skimmer. this should be a much better setup. And unlike other reactors such as GAC or GFO, I only need to change this out every 6 months or so.... I had considered changing to carbon dosing, but I have had good success running biopellets.
There is no room outside of the sump...so I had to place it in the sump.
