How do you regenerate GFO?
Dream 525 gallon peninsula display with large fish room.

Aquarium Chemistry: Regeneration of Granular Ferric Oxide Media with Sodium Hydroxide
For aquarists who keep non-photosynthetic corals that require massive feeding, have large tanks, or a dense fish population the costs of regular GFO replacement can be significant. With a few simple tools and techniques we can easily regenerate GFO so that it can be reused several times over.

The basement is really close to being done. I spent this weekend alternating working in the sump room and painting the last of the doors. All that's left is some work in the bathroom and doing some electrical work, light switches, outlets and such.
I haven't posted much of the frag system in this thread as it is a separate setup and not the point of the large tank build. Most of my work this weekend revolved around it so unfortunately not much was done with the display. I'm hoping that between installing the rest of the lights over the frag trough I'll have time to do a water change on the big system this week. I really need to get the GHA under control in there and devote a decent amount of time to the water quality. The combo of the ATS and carbon dosing does not seem to be enough to handle the level of feeding input. One of the projects on my todo list is to rebuild the ATS on a new design. I just need one more day in each week, time is hard to come by lately.

This is awesome, wanting to build myself one of these someday
Ok, I'm here to say. Regenerating GFO on a semi industrial scale is not practical. Again, just saying. 
We need the story......Ok, I'm here to say. Regenerating GFO on a semi industrial scale is not practical. Again, just saying.
I go through way to much to be cost effective to use. And I don't have the time to regenerate through reactors.
I'm going to need to figure out another solution.

Lanthanum Chloride?
That's what I'm thinking. I just need to figure out a safe way of dosing it while collecting the particulate. I've lost fish using it, don't know if it was coincidence though.
any update?
Other than the back overflow box popping loose from the aquarium, leaking 20-30 gallons on the floor, everything has been status quo.
It popped on a Saturday and MRC/SEA came out the following Monday morning. This was the week before Memorial Day.
Lack of time has been my biggest issue. Between work, the health problems, my mom & step dad living with us for 90 days, a retaining wall, yard work, a wife with a gimp knee that needs scoping... and... and...
Finding someone local to help with everything has been less than fruitful. Everyone is too busy with their own shit, so I've take the I'll get to it when I get to it approach.

Yup, hobby gets put on the back burner when life hits. We all get that.
So, did MRC fix the issue already and I guess all good now?
Give us an update, Princess...
