Pot scrubbers would need to be used in a wet / dry setup (same way you would use bioballs). There is not a lot of room to create a wet dry filter. With a wet /dry setup, the water would flow into a filter pad, then onto a drip plate creating a rain effect onto the pot scrubbers. Having a torrent of water on them renders them effectively useless as the good bacteria do not populate them.

I think my pump can put out slightly more than my overflow could handle if the valve was fully open, but even if it was open it's not very high flow for the system so i dont think torrents of water should be an issue. The volume of the first chamber is a little over a gallon submerged with 3" above it. I made a cover last night out of acrylic and i was thinking about making the inlet end of it depressed w/ holes to allow water to flow over it and onto the filter media. a completely submerged porous media would work as well right?

I would do a tray with filter pads on the top level, a drip plate with lots of holes in to rain onto the bioballs and then submerged I would use ceramic rings or noodles (whichever you call them).

If you do a wet dry then the flow needs to be fairly strong from the overflow to allow the water to pool a little bit on the drip plate, this will allow an even flow of water across all the bioballs or pot scrubbers.

video of my progress on the refugium.. i guess i dont like to take too much time with things once i decide i want to do them.. this project was actually me being relatively cautious and careful

jewel cichlid tank with refugium/sump - YouTube i just have sand in it, and seachem matrix for filter media in there right now, the LFS guy sold me on it. i have a cover on it that isn't in the video.. just some neatly cut acrylic. gonna pick up a light for it hopefully tomorrow and then get plants. i put my bio wheel in there temporarily too because i was nervous about having no established biofilter media besides the tank substrate and decor. i am most likely going to shut it down briefly and cut the inlet to the overflow 1/4-1/2" as well..the tank water level is way higher than what i am comfortable with. i'll post some pictures with lights and plants and everything cleaned up. for aesthetics i will most likely get a submersable heater so i can put it in the sump, and then a black backdrop.

new pictures :) picked up a light today for $20 and modified it so it sits nicely on the acrylic cover of the sump facing downward. i took the overflow off and sawed down the inlet so the water level is perfect now.. i'm going to buy plants for it hopefully tomorrow, just chucked the beaten up moss ball i had in there for now.

Talking

Any way to upload really high quality pictures? Ah i just noticed jpeg and zipped files can be larger. I have a 14megapixel camera and the pictures were all too big.. pictures from my 5mp phone aren't as nice. Also my phone indescriminately posts them as landscape.. heres the latest picture of everything. I think this thread might be more appropriate for the DIY section.. might make a new post in this section of a video of the finished set up.

You need to take them off the phone and then post them to get them in correct orientation.

I would perhaps as well look at having the sump lights on when the tank lights are off.

Yea i had been loading them onto my computer to upload them except for one other i think, but my computer has some malware on it so i'm not using it until i get it fixed or get a new one. as for the lighting, i haven't gotten a timer yet, probably the last thing i need to do still.. then i'll have them offset. I guess i could start doing that now. Going to read up more on lighting :)
