Messing around with an in-cabinet wet/dry under a bottom-drilled 90g with one 3/4" return and two 1" drains. Feeding the drains are dual Durso-style standpipes. The standpipes are 1". I believe that the original Durso design used 1 1/4" pipes reduced to 1" and so I'm reducing my two 1" drains to 3/4". Keep in mind this isn't a reef system and I'm not targeting a very high turnover rate through the sump; 300-400gph would be fine.
Now my noise problem is not with the overflows at all. They are actually pretty darn quiet. The major source of noise seems to be in the drain lines between the tank and the sump. I have short sections (about 8") of vinyl tubing connecting each drain bulkhead to a horizontal section of 1" PVC which in turn connects to the sump (see attachment). I think the noise is mainly from the PVC pipe.
I wonder if an alternate design could cut down on the noise. First, do you suppose using all vinyl tubing from the bulkheads to the filter would be quieter? Or, do you think that Loc-Line tubing would be a better choice?
I've thought, too, that I might just wrap some insulating foam around the PVC pipe.
I have some space constraints to work around - the drains are only about 8 inches apart and there are only about 10 inches between the top of the filter and the bottom of the tank. That horizontal run of pipe is about 20 inches.
I'd love to hear what you all think. Thanks.
