Sump/Ref Design "Take 2"

Do they sell 100% submersible pH probes? I know the ones we use in lab are not submersible and only about 1" of the tip should be in the liquid. Maybe reef probes are different. WHy'd you stick the skimmer before the fuge? I'd let the bugs in your fuge have first crack at the nutrients before letting the skimmer takes care of them. Otherwise it looks nice

 

I wouldn't put the temp probe right next to the heater, and I also wouldn't put rock rubble in the first chamber - that will just end up being a huge detritus trap.

 

Are you trying to get the skimmer section to run at a lower level than the refugium? If so, the water is going to have to get higher than that final baffle (left refugium "wall") in the skimmer section in order to make it into the refugium.

I let my skimmer take care of all detritus, and whatever it misses, I siphon out occasionally.

 

You may want to place a value on the output as well.  This will cover you if your pump that goes on there moves more water then your overflow can handle.  If this does not happen then you can leave the value full open.  Plus it is always a good Idea to be able to shut off all piping that moves water.

 

i have basicaly the same setup minus the first bubble trap and mine is doing just fine. i just wish i would of made my first chamber bigger and my fuge smaller. oh also i have no valves on mine right now /DesktopModules/ActiveForums/themes/_default/emoticons/sad.gif first time using/building a sump, i had no clue exactly what i was doing, but knew it wouldn't be permanent.

 

One small detail, the temp sensor might be close enough to the return pump that your readings may be off. Slightly, I know, but if you are putting the work in it might be worth noting. I would consider putting it nearer the skimmer.
EDIT: It helps reading subsequent posts before replying, LOL Seems someone already suggeted this and you changed it
