Is this a good design/placement for refugium, reactor, skimmer?


Check the attachment, I'd have photobucketed it but photobucket is not coming up for some reason



Im thinking of a way to redesign my current sump to incorporate a 2nd bigger sump for a bigger skimmer and was thinking that everything else, carbon, phosphate media, UV sterilzer, refugium should all come before the skimmer. What do you guys think.

that is true is should come before the skimmer but with a true "refug" it is a slow flow through the refugium. With the water coming straight from the tank in to the refug I dont see how it would be slow. you almost need a baffle from the tank in to your sump first and then have it go in to your refug (ie cheato's, rock, sand, etc.)

imo I very well could be wrong, wouldnt be the first time.

We need a better pic and description. Right now it looks like it may or may not work. Depending on the flow, you may need to T off the drain as Bone mentioned it needs to have a lower flow rate so lets say it's a 20 gallon section, you don't want 600gph going through it.

Also is needs to go via gravity, you can't feed the second sump with another pump, it is almost impossibly to match flowrates and somting will flood or starve.

So Drain to fuge and one to skimmer section, fuge gravity fed to skimmer sump. Po4 reactor on a closed loop in the skimmer section...

If you redo the pic, with a description of everything, I can help more if you like

Ill take some pics of current setup but the drain right now actually does have two bubble diffusers/plates that slows flow down alot,

There is also two more bubble diffusers on the other side of the refugium that slows that side down, gimme just a minute and I'll take some pics

ahh, the old catch 22 with the refugium. this is why i do not think that they are beneficial for our systems. if you put a refugium before the skimmer then all of the goodies will be skimmed out before the tank. if you put the refugium after the skimmer then the fuge will be starved for nutrients because the skimmer will be pulling them all out.

just leave the are empty and allow it to become a settling tank. that way it is easier to siphon out the detritus that will fall then during the time between water changes. it is a lot easier to siphon out an empty are then one full of LR/sand, and other silly stuff.

I actually was considering that as my first option, I only will add plantlife if I have too, first thing bigger skimmer, 2nd thing phosphate reactor and 3rd the refugium,



Here are some pics of the current drain

Drain into refugium,, currently occupied by G3




2nd chamber of refugium where I might house the phosphate reactor

(currently occupied by the crappiest skimmer known to mankind)





Im working on the 2nd sump as we speak but what I would do is take the 2nd chamber where the phosphate reactor would be then connect the current bulkhead that goes to the return pump to my UV which would be turned sideways so that the lenght portion of the UV goes towards out the back of my stand, then my 2nd sump will be on the floor connected to the UV outlet, ( the floor being 2 inches lower than my first sump will help gravity feed but regardless they are on a lvl surface so the 2nd sump I believe will get plenty of feed water.


The 2nd sump will only house a large protein skimmer which will be near the drain from the UV then after the UV another set of bubble diffusers and which leads yet another small chamber so I could actually put something after the Protein skimmer if needbe.


Hope all this makes sense.



Also about putting the fuge and phosphate reactor before the skimmer won't fuge trap detritus if there is a bunch of macro in it? and the phosphate reactor being before the skimmer,, how will this affect the skimmer performance itself? I know carbon makes it go nuts but Ive never used phosphate remover before.




Thanks guys !

Mike, I'm sorry, but I'm still confused. Sorry.

It sounds like you want to gravity feed the second fuge or pump to to it through the UV. This won't work. I would split the return, one to the skimmer section and one to the fuge section... To make things easier, can you draw something up on paint or anything and I'll add to it, or offer suggestions

Ok here it is, its not a perfect drawing but you get the general idea,

main thing I think you were missing is that the UV is gravity fed and is the gateway/path to the 2nd sump, 1st sump is in the stand a few inches above the ground, 2nd sump is on the floor a few inches below the 1st sump.

my concern is the the uv sterilizer would be able to pump at a sufficent rate. I know that water seeks its own level a the second part is 3 inches lower but I dont know that much about the rate.

the inlet and outlet of the skimmer are really big up to 2 inches although I do have them down to 3/4th inch right now with adaptors.
