I promised Kat that I'd post a picture of my DSB bucket. I haven't had one before and i cant see how it could hurt to try it.
The bucket is also a fuge, it feeds off of my return, controlled by a valve and set to a very low flow. After it returns to the sump.
view of the sump, its 20 long. The red valve is for fuge/dsb flow control. Its set so low that i cant visually see any flow, may be 4 gallons/hr.
I love DIY and here are some things I have finished in the past week:
ATO - radioshack relay, project box, red/green lightup switch and extension cord cut in 1/2. total cost about $16, red light to remind me to turn it back on after a water change = priceless.
New overflow drain that's extremely compact and silent. It emits a low air-draw whisper but its too low to bother anyone. Combined with sump silencer ( red arrow in second pic), I have no gurgling in tank or sump with mag 5 running full on. total cost = under $10
