Keep replacing filters every week?

My old tank I had when I was a kid was a 10 gallon with guppies and tetra's in it.

Im pretty sure it was overstocked, but the filter could go 3 weeks before needing to be changed.

Now my 29gallon....

I jsut addressed an algae and plant browning issue... but noticed that my filters are lasting 1 week.

Im using the basic Aqueon 30 gallon hang on the tank filter system that came with the tank.


My tank is fully planted.

Stocked with:

4 Female Betta's
2 Dwarf Gourami's
4 Cory Cats
1 Rubber mouth Pleco (its about 2" long now)
4 Zebra Danio's

I change 25-50% of my water every Sunday, and after I change the water I put in a new filter (after all the sediment and stuff in the tank has settled or gone into the old filter)

Anyone have any ideas?

What I do, because I have the same filter for my dp tank, is take out the filter and vigorously shake it in the dirty water I vacuum out during my wc. you'll find that after just rinsing off the debris, the filter will work well once again!

1 Otos, 6 Guyana Leaf Fish, 2 Malayan Leaf Fish, 1 Orange Head Tapajos, 4 Bronze Cories, 3 Peppered Cories, 2 Panda Cories, 1 Skunk Cory

Yes, stop wasting your money. You do not need to replace filter media until it literally wears out/falls apart. "Cleaning" by rinsing the media is a different thing, and this should be done as often as you need to for the biological load in the aquarium. The water must freely flow through the media and pads; if it is blocked, the media/pads need rinsing out. The water must not be impeded or find alternate routes around a clogged pad.

Rinse the media and pads and replace them. Some will suggest doing this with tank water, I don't bother because I have plants. You mention plants, so if you have live plants in the tank that are growing, there will be more bacteria on surfaces in the tank (plant leaves, tank walls, substrate, decor) than in the filter anyway. Plus plants consume more ammonia than bacteria can. The filter is only needed to circulate the water and run it through the pads to remove suspended matter, in other words, keeping it clear. The plants will do the major job of cleaning the water.

I use the same filter in my 20 gallon tank. I just rinse it out in the dirty fish water. I beleive the company wants you to change the filter monthly, but don't do it as you waste your money and your tank needs to cycle again.

I usually do rinse it out, usualyl in the sink where I can use a higher pressure water flow. Even doing this, after putting the filter back into the tank, the flow is so limited it all just bubbles over the side.

I guess next time Ill try cleaning it more throughly.

I did get lucky though, and picked up 2 6 packs for $10

Oh no! Don't rinse it in the sink! You kill all the bacteria that way! I really don't know what the problem is...do you keep carbon in the filters? I cut them open and dump all the carbon out when I first get those...Now I just use the big bulk filters and cut it to size.

It's supposed to just bubble oer the side. "natural waterfall flow" I beleive it is. The aueon's are not high current filters.

My 29g, my 20L, my 10g and 5g, all have the same filter from well over a year ago. just either open the filter (or on the penguins I had to bust the back out) to get the carbon out, then every water change I shake the filter in the old tank water. Never replaced the media any of them unless they were out of service for a long time, oldest one is oooooh a year or so old.

my 110g I have the same problem, but it has 2 baskets. So I rinse one in the sink but dont touch the other one. next W/C I rinse the alternate one, so on and so forth. just shaking in tank water aint enough for those puppys :)

to be honest, as long as ALOT of water isnt bypassing the filter I wouldnt be too worried about it unless it gets progressively worse.
