I agree, fuges can be bad for collecting detritus.
What you can do though when you do a water change is take the rock out of the fuge and shake it out in your old water to get some of the detritus out. If you do this it wont be a problem.
Use minimal rock if you are growing pods in there and wont want to take the rock and shake it out.
Ok, thanx for the replies so far. I do have a bunch of pods in there, in a couple of piles of rubble rock that are in the corners. I think I have about 25 lbs of rock in mine now, do you guys think that maybe I could break up the larger pieces and make more rubble piles? That would also give me the choice of more rocks to put frags on. What do you think?
The pods will love it if you made a bigger pile of rubble rock, but if your fuge seems to catch a lot of detritus it may be hard to clean. Then again if your running sand in you fuge if you probably are, the detritus will settle in there more than the rock most likely. Probably no sweat.
Well....I have just under 30 pounds or so in my fuge.....and only live rock in it (no sand or other substrate). I want the extra filtration the live rock provides. I have 3 - maxijet 600s in there for circulation, and siphoning up the detritus is pretty easy - it has become part of my regular maintenance, as did blowing the detritus off the rocks. The goal for my fuge is filtration, pod propagation, and extra water volume (+ the sump water volume).
It is a maxi-jet 600 pumping up from the sump and gravity fed back into the sump. The original plan was to be gravity fed to the tank, but I have changed my mind (imagine that). I like the current location of it on the middle shelf of the side cabinet. It makes it really easy to maintain.
Here is a shot shortly after the uncured rock was placed in it.
I am still staying where I was for now looking for the right place. I am going to make some piles as soon as I get some rubble. What kind of macros do you have in the fuge. also mine is under the tank because of space limations. I do know that I still get pods that make it past my pump. I geuss the only evidance that I have is a fat and happy green spoted Manderain.
LOL - the soda can was for size comparison . No macro algaes in my fuge....I didn't want to deal with any toxin issues. Hopefully, my maintenance and "waste removal" will be sufficient enough that I won't have a need for macro nutrient export. I also have a ton of rubble in there.
I have about 15Lbs in a circle in the first section of the sump. The overflow empties into the middle of it. The turbulence keeps them relitively free of detritus. There is big ball of cheato in the next chamber down, but I dont have them in the same spot. Just my method.
