Quite Overflow Box

- Start date
Mine isin't have a drain pipe and it sounded like a toilet flushing all thie time, I added a piece of 1" ID PVC pipe to where it was keep the water from falling into the overflow. This helped alot, then I added the foam. that helped more. Put a box that I keep my FW filters in on top of that and now all I hear is my skimmer and return pump...

IMO I would not use foam there or anywhere in the water column--great collectors of nitrates, phosphates and other dissolved organics.

I had the very same problem when I first set up my reef. I built a Stockman standpipe for each of the two overflows, like you have...with the U-tube...and it completely silenced them. If there was any complication at all, it was with the size of the hole on the top of the standpipe...I had to try various sizes. In my case, only a hole of 2/32nds of an inch completely silenced the overflows. Any bigger or smaller and there was still some...not a lot...but some noise.
If the foam insert is cleaned once a week there should be no problem with it collecting to much detritus. Foam inserts will collect detritus after a while and it can break down into nitrates. Like I said if kept clean it won't be a problem. Foam inserts can't collect dissolved organic matter because it is dissolved. Dissolved organics can only be removed by protein skimming and adsorption media. Foam insert performs only mechanical filtration not chemical.

hmmm--I have been lead to believe that protein skimming is mechanical filtration

I use dual dursos, works very well, dead silent. But it took some tweaking to get the water hitting the sump to quiet down, but it is possible. I found trial and error to be my best friend during my plumbing adventures

well put.
I always thought this--but was corrected so many times by others when I first joined RC that I started saying it was mechanical instead of chemical

i wonder if some of the confusion is around the difference between mechanical(chemical) and biological(live rock)
Alot of reefers state that the only mechanical filtration you need is a protein skimmer and the only biological filtration needed is live rock/sand bed.
In this way they are lumping together filter socks, canisters, hobs, etc etc with protein skimmers, not focusing in on the differences in the processes that these use
Cap'n I wouldn't be too concerned about it . I think its semantics. Is it chemical because it binds materials that are attracted to the water air interface to the bubbles because of opposing charges on the materials and the water molecules? Or would a molecular change need to occur such as in denitrification to be chemical,?Wait a minute that's biological oops. Carbon attracts molecules the same way bubbles do doesn't it. Now I'm confused. I think knowing what's going on in a certain process is alot more interesting anyway. And I think the way Percula 9 wrote was clear and well put.
