Flow...

Hi all,

I want to dampen the sound to my tank by reducing the overflow by half, currently I am pushing near 6k of water, and as you can imagine is not very quite,

so...

Does anyone thinj it would be a good idea to do this moving the pump for just internal flow?

Thanks,

Sean
 
As odd as this sounds, if you cut it in half it will increase the noise as you will have the same amount of water falling over a smaller surface area.

What you should do is increase the size of the overflow thus increasing the surface area so the water will flow slower over the lip, or you can slow the flow rate a little bit.
 
Through all the problems that I having at the moment with dying fish I have being doing everything that I can to possibly better their chances of living, even if not to much avail,

In doing this I have accidently wet one of the plugs to one of the other pumps and the noise is much better. This is why I am asking, If I can get this main pump internal the noise would be much better, my problem is, (other than my fish dieing :( ) is there a recommended amount of water that should pass through a sump.

Thanks for the response,

Sean
 
nope, probaly my set up....

Water gflows over the over flow down some pipe into a type of coffee filter which fills up and over into medi balls (this part makes the noise) so when I reduce the flow it trickles down the side of the filter bag not rushes :) sort of like a water fall!!!

hope this makes sence, quite hard to explain!
 
I think I understand. Quick question, are you fixed on keeping the bio-balls? If this is a reef tank and you have a good skimmer, live rock, and are faithful to frequent water changes there is no need for the bio-balls. :)

You could Make it so you have no trickle or rush if you do a little redesign.
 
To be honest with you, I do not know what to do at the moment, I had a perfect 55 for a year, upgraded and have had nothing but problems since, I have bought everything I can think of to improve but still have problems, I cant even manage to get polyps to stay alive, and don't know why. It is only my passion for this hobby that keeps me going!

And yes any ideas to redesign are welcome, I was thinking of removing the coffee filter extending the pipe into the water so removing the noise?
 
If your noise is from the over flow try this and see. Take a straw and hold on to the end but leave the hole end open place the straw in the drain down it and at an angle slowly move it and see if it gets quiter move it up and down and hold it at different spots till it gets almolst silent if that worked I can reccomend a more permanent silent fix just let me know by p.m. me. slowing down your flow rate is not the answer IMO!


I agree with the above advice Take out 2 media -Bioballs every other day till they are all gone If rite your Nitrates are high and this is a major contributor.

also Here is the ref central sump calculator

Thanks for the info guys that has been a real help. Kind of what I was thinking, by removing the coffee filter and extending the pipe below the sump water line will dramatically reduce the noise me thinks :)

My nitrates are always 0 due to the little load on such a big tank, do you think that it would be a good idea to remove the balls event though I do not have enough LR - What I was thinking was to reduce the balls after I had enough LR?
 
I'd say that if your nitrates are at 0, then just leave it alone. If you get more live rock and do increase the number of fish in the tank, then you can reconsider. If it's working right now I'd see no reason to change things.
 
Hmmm....so, after having a successful reef, you set up a bigger reef. In the bigger reef, you had noise from the plumbing that you hadn't had in the smaller tank AND you are having trouble keeping fish and inverts like coral alive?

When did you first set up the newer, larger tank?

Okay...how long did the new tank take to cycle?

What did you put into the tank when you first added live stock?

What livestock's in there now?

What are your water's readings?

Don't give up, man....not if you love this stuff.
 
Thanks for the support,

7 months ago I moved house and upgraded a 55G to a 200g with new noisy sump :)

Everything was fine for 2 weeks, then the system decided to cycle, the filters, some sand and about 1/3 of the water from the old tank went into this system.

Everything died except hermits and a snail :(

The tank took a further 2 - 3 weeks for params to settle

I left the tank for a further month then started to add live stock
I added a polyp coral, painted lobster, 2 pipe fish, enemone,

Everything looked fine when it went in

Overnight, lobster is dead, pipe fish are dead, enomone has melted.

Leave tank for another month test testing for Copper and anything else I can think of, ran poly filters carbon and various sponges just in case there is something in the water.

All this time hermits and snails are ok

I now add 2 yellow tail damsels, 1 marble tooth blenny, scarlet lobster, 2 black and white percula clowns, Regal Tang, Copper Band, Blue cheek Goby These were added over about 2 - 3 weeks

These are slowly on the decline...

Sometimes I get the feeling that the water is not right, but then again, my gfriend thinks that I am over caring and worry to much,
I do have coraline both red and purple growing and there are those crabs and snails...
 
Hiya, thanks for asking,

I am down to the clown, damsels and r tang, I have been out today and bought a new heater as I was doing a water change in the middle of the night yesterday and the water was about 30oC... I think the heater may have been sticking?!?!?!?

The water temperature is ok now, but the fish are still breathing at a rate of about 70 - 80 per minute.

I am doing a 5% water change every day, this is the most I can do due to the cold and my RO unit (did not know) I am feeding them about 5 x a day with garlic and frozen food (read in another thread that it may be good for ich)

The clown is behaving quite strange, he is ok most of the time, but during the day after all lights are on for a few hours he lies down on the sand like he is dieing yet recovers at night - does this give any clues, are the lights too bright?

Another curious thing was that the regal tang had ich on it yesterday no doubt due to the stress of heat, yet he has got rid of it, so kinda strange that other bacteria may be doing this if the health is that good?

It sounds like there was a problem with the thermostat part of your heater since the temp was at 30 degrees C which is 86 degrees F....pretty high. That alone wouldn't be the cause of all of your fish health problems though. For them to be breathing very hard even with the temp at a good level, it sounds like you have an insufficient level of oxygen in the water for some reason. The warmer the water the lower the oxygen level but with normal temps the water should possess sufficient oxygen that the fish wouldn't be struggling like that for air. This could also be due to high CO2 levels. Have you tested the pH of the water? What's it at now?

What you're doing is fine, though with such frequent feedings, make sure they're lean and mean or you'll wind up with elevated nitrate and or phosphate readings and the attendant unwanted algae growth.

I don't know what the explanation is for the clownfish doing that. It is strange, though I have an Anthias that sometimes rests on the bottom of the tank and otherwise is healthy and shows normal behavior in every respect.

The fact that the Regal Tang had ick and recovered is a very good thing since it shows that the fish is in otherwise good health and whatever the problem that you've had is, it doesn't appear to be overwhelming even an already stressed fish. I think you've seen the worst by now.
 
I will get an oxygen test kit tomorrow, just out of curiosoty if the water was low on oxygen would the fish not go to the surface or is that just for other problems?
 
I don't know for certain but I believe that since many saltwater fish are deeper water fish than say, freshwater fish, their respiration rate might go up rather than for them to seek the surface.
