mag 9.5 or quiet one 3000 for 75g

[kirtdog]

I just set up my 75g and I am getting a lot of "toilet flushing" on my drain. I have had to turn the ball valve way down on the return to get it to stop. I have a quiet one 3000 pump a storage tank downstairs. Do you think I would get better results with that pump. The overflow drain is rated 600gph. It is a megaflow overflow. I think the mag 9.5 might be too much. Any opinions?

How far is the pump pumping water to the tank? 4'?

 

[kirtdog]

probably about 4 ft. Should the drain pipe be below the water surface in the sump?

 

[Ricunger]

I keep mine below the surface... The water is really annoying when i had it above the surface. I would move it down and see if you get better results. As for the pump i would keep it on. After the head it should be 800gph from the 9.5 I think it should be fine dialed back. The Quietone 3000 is 750ish gph so after the 4' of head the gph will be below the 600gph overflow.

i just switched it out and i had to dial it down too. I have the return hard plumbed and the drain is a piece of vinyl tubing. It is under the surface and I am still getting the flushing...what now? Am I missing something? Ignore all of the purple primer on the union...slight spill

 

[Ricunger]

What bulkhead are you using? I beleive they come with 2 different ones from the factory. Also try to move the hose above the water surface in the sump... the last thing i would try is extending the standpipe as it way not be high enough.

 

[Ricunger]

Be sure to try the drain pipe above the surface as the air might be escaping upward.

Ric,
The drain is 1" and the return is 3/4" I will try to move the hose up above the water surface. I thought it would be noisy with the running water.

 

[Ricunger]

Thanks for the photos i just seen them now. The flow of the drain is taking a beating with 2 90 deg bends. I would swap them out for some 45's if possible. I would say your drain is able to handle about 500gph or less with the 90's on it.

 

[kirtdog]

the return is the one with the 90's. I plan on hard plumbing the drain once i get it sorted out

 

[Ricunger]

My fault... i wasn't going to ask why you had a ball valve on the drain.

Well it is still restricing the flow on the return. It shouldn't matter. I would keep the 9.5 on. Let me know how the sound is after the drain is raised.

I have a 9.5 on my 75 and I dont have to tune it back at all....porbably about 3 feet of head

 

[kirtdog]

hmmm....the hose is now just above the water level and the gurgling is gone but it sounds like someone is filling a bathtub....I am able to have the ball valve full open now.

 

[furman589]

Have you tried placing a T on your drain hose? I found that to help my noise problem. It is fully underwater and there is minimal noise from bubbles

 

[kirtdog]

where do you run the other end of the T? I am going to run PVC tomorrow. I am out of hose from trimming to experiment...lol

 

[furman589]

I dont have it run anywhere, its just underwater close to the water surface. it doesnt eliminate the noise but it helps a ton

try dumping into a 100 micron filter bag.work wonders for noise,micro bubbles and polishing the water

 

[kirtdog]

thanks dan,

where can I get a filter bag? should I still the drain pipe under water an inch or two,

I appreciate all of the replies and suggestions...thanks everyone. This is my first tank with a sump. I built the sump from a 30g and now i am trying to sort out the plumbing. My previous tank just had an HOB filter. Here is a pick of the previous tank that I lost recently due to 3 day power outage. On a positive note, it gave me a reason to finally put together the 75 that has been sitting in my garage for the past few months

 

[Ricunger]

Sweet tank! I'm sure your 75 will be even nicer!

The bags can be bought at something fishy or champion lighting
The drain can be above the water surface when a bag is used
