STAND PIPES

[Psylant]

If it is just crud settling in the bottom what about placing a very small powerhead in the overflow box? I have never used a sump, but it that seems like an easy solution to me.

Every once in a while I use a long stick to stir it up, it will float up and get sucked into the pipe.

Mine doesn't get too bad, usually stir it up every other month or so...

the discharge line/lines from overflow need a flow control ball valve to keep noise down ajust valves till sound gows away but still kiping flow good

thats a very bad idea. by restricting the drain lines, you risk the chance of a flood if your flow ever changes for wahtever reason. better to have a bit of an overhead then dialing in to the flow that your pumps pushing. unless if your running a herbie style and have an emergancy drain.

Herbie overflow, little info here in the search but a lot over on reef central. Very silent and I clean gunk on the bottom, inside the overflow once a month.

Do a normal 2 hole herbie. 1 with a low stand pipe with the gate valve. The second pipe higher. Tune the gate valve so that water trickles in to the second pipe. Silent operation. This is a pic of my 120 i drilled. I can explain to you how they work if you want. Tanks with build in overflows I always run the 2 stack herbie. My 120 has a danner 9.5 and I barely hear a hum. No water noises at all. Since I drilled the tank I added a second back-up just because it was 6$ for the sch 80 bulkhead. Just one of them drains the tank faster than it can be filled with the pump.
