Alright, so this is the part I was supposed to do when I started the tank, but was more intent on getting drunk after all the other stuff I did, so it never got done. And it's a good thing, because it gave me some time to think about how to approach it.
This is going to be my dedicated refugium. It is going behind the display tank and will be fed by a manifold I have behind the tank off the main pump and will be gravity fed back into my return compartment.
Why am I doing it that way? Well, if I send my tank drain through it, the flow will be way too mucho...gringo.
With the tap off my manifold, I can control the flow of water with a ball valve to get the flow I need and increase my return pump speed so the flow to the tank isn't altered by that.
Most of what the refugium dumps into the return compartment will go to the tank, and yeah a small amount will return to the refugium, so that's fine.
It looks like a piece of crap, but I just have to wipe it down. It's really like new. It's basically calcium film now that was all eaten away with some citric. In this will be 5 lbs of miracle mud, some red gracillaria and I will be seeding it with a scoop of another mud refugium, pods, phyto etc until it's populated.
When I am behind the tank, It will be facing me as shown. So water will enter the right side with a 1/2" pipe dropped into the nifty bracket on top for support, and will exit at the front left chamber through a 1" bulkhead drilled right through the side of the refugium at the proper water level where it will drop into my return compartment over the back of my sump.
Anti-siphon precautions will be taken on the feed line for when I kill my pump. Everything will work great.
And sump capacity is no problem. Doing it this way ensures I'll never have any floods.
This will likely be the most important part of my system. It will produce food, export nutrients and supposedly provide proper trace elements....the third part I can't prove. All I know is that my most successful tank ran on this method and it was awesome.
I picked up that little reef breeder refugium light for like 40something bucks brand new.
Stay tuned! I think I'm gonna brave this job tonight. LOL I really want to have this up and running as soon as possible.
