phosban 150 noise

[dragonfisher33]

so i bought a Maxijet 600 and a Phosban 150 for the tank. when i hooked them up together, there's a noise coming from the pump. i then tested the pump by removing it from the hose and the noise is gone. it only happens when the connections are made. therefore i conclude that the noise is caused by the backflow of water as the result of the ball valve. does anyone has a similar issue? how should i approach this issue?

Install a T off line to relieve the pressure.

so, how is my setup different from other people's? I have not heard anyone needing a tee to reduce the pressure. the extra tee is not visually pleasing to say the least

 

[dragonfisher33]

so no one has the same problem that I'm having?

Back pressure on pump causing your noise

Back pressure on pump causing your noise

right, I understand that. but how come others are not having the same issue, or do they?

what's the proper pump for the reactor? I followed the recommendation of others. therefore something is different between my setup and those of others

 

[Reef Junky150]

Possibly just something tolerance wise with the pump you received or unnoticed by others? Your putting more back pressure than others on the pump? A lot of variables. Can you see about switching pump from supplier?

so I have tried Minijet 404, Maxijet 600, and Rio 600, and one other misc pump. all of them gave me rattle noises

 

[Reef Junky150]

Sounds like you may have more than normal back pressure? I wonder if someone else who has one can chime in compare your installations etc.

 

[Reef Junky150]

I use a mj1200 to feed bio reactor and skimmer and no matter how much bp I put on it never any noise.

 

[dragonfisher33]

just for reference purpose, the reactor is hung on the back of a 40B. so the most that the pump has to push is ~16inches

 

[Reef Junky150]

How far closed is your ball valve for adjusting?

 

[dragonfisher33]

this is the ball valve


this is Maxijet 600 with the barbed tee. FWIW, the koralia and the Maxijet are not touching each other, they just appear this way in the pic

 

[Reef Junky150]

Even with the tee it makes the same noise or did this resolve the problem. Tank size? Are you running less media as to close valve more as to adjust in properly?

tee solved the issue but it's an eye sore. i would've left it like this if i had a sump. the 40B is my main tank. it doesn't have a sump. i'm running the recommended amount (~1/2 cup of bulk GFO) for a tank that's got ~35gal of total volume of water.

 

[Reef Junky150]

I think that may be the problem. Running a 1/2 cup is not very much in turn your putting more back pressure on the pump trying not to sand storm the gfo. A tee is your best option. If possible try hiding some of the plumbing and tee behind rockwork or glue zoas or coral to it to help blend in?

 

[Reef Junky150]

Also get a black tee?

so are you saying that i should put more GFO in the reactor? i thought more GFO will cause burn tips on the sps corals.

 

[Reef Junky150]

No, only recommended. Less at first in some cases to prevent sudden expulsion of po4. Your tank size is smaller than most that use that size reactor in turn your using less gfo. That causes you to use less pump pressure to tumble it. A smaller pump is what you need. Or keep what you have working and hide it.

We have same reactor and run a RIO 600 and it's as quiet as a mouse, no noise what so ever.

Sorry ur having prob......hopefully you get it worked out..
