Question about noisy aquarium pump
« on: April 20, 2008, 08:04:51 PM »

I have a power filter for my 55 gallon. The aquarium contains 4 fantail goldfish and a good amount of live hornwort plants. The tank doesn't stay clean for long so I must do weekly water changes. I have an airstone which is necessary right now because I have to unplug that awful power filter when I'm at home. I cant hear myself think! It wasn't this loud when I bought it but each time I turned it off to clean it out and then put it back together it got louder. It still pumps water through but the noise is almost unbearable now. Is there anything I can do besides purchase a newer, more powerful pump this time. The pump is made for 30 - 60 gallon aquariums but goldfish are extremely messy when put in conjunction with live plants so I wonder.
Please help.

Hi   -how old is your filter? I'm wondering if there is something worn or broken? As I only have xperience of internal canister filters I can't give you a definitive answer but can offer some suggestions so apologies if anything I mention is incorrect, I'm just guessing here!

Make sure there is not any air getting into contact with the impeller-air is very harsh on filer systems & will make a lot of noise-I have a couple of canister filters & if I don't prime them properly after I switch them back on a lot of air is trapped inside & forced against the impeller which makes a terrible racket!

another possibility is like the above poster said-check for sand residue if appropriate & if the working parts are ceramic there may be some surface scratching that is making the noise. You may find the spindle/shaft/axle for the impeller is made from ceramic material & is broken-or not sitting true in it's housings?

If you cannot correct the problem you will have to get yourself anew one but don't turn the old one off until you have the new one. It is vital to maintain filtration constantly for Goldfish. You can put the established media from your old one into the new one so there will be continuity of the cycle. If it is bigger then the old material will help seed the new.

You should be doing weekly water changes anyway.Your water problem is probably because you shut your filter off.They are designed to be left on 24hours a day,and this is how they should be used.

The only thing you could try with your filter is to replace the impellar.

You are going to need to buy a new filter if you can not fix the one you have now.At least 1 more,with enough filtration for at least 100 gallons.A canister filter would probably be best for you because you have gold fish,(which are very messy,as I am sure you know).If you cannot afford a canister,2 Marineland Emperor,or Penguin, power filters would probably work too.If you buy on line,it will save you a lot of money.
