Cleaning a sponge filter

I got a sponge filter running for a couple of months now. I was wondering how often it needs to be cleaned. Is it enough to just wash the sponge in water?

Cleaning a sponge filter is simple, all you need to do is squeeze it out in old aquarium water. I clean my sponge filters every few weeks or so.

whenever you do a water change, take one of the old buckets of water and squeeze it out inside of that. That way it keeps all the bacteria alive on it.

Subject: Larry LaPrise dead at 93

With all the sadness and trauma going on in the world at the moment, it is worth reflecting on the death of a very important person, which almost went unnoticed last week.

Larry LaPrise, the man that wrote "The Hokey Pokey" died peacefully at the age of 93. The most traumatic part for his family was getting him into the coffin. They put his left leg in. And then the trouble started.

u do it basically as much as it needs
u can check it every week or so its not that hard to tell most have handle type things u just pull it out look
if it needs it u clean it if not then don't

i usually do mine about every 9-10 days because i have angels and water quality is crucial to their growth

over feeding can lead to dirty water which will also lead to more frequent changes

i have a dog named fish

30g long

55g -planted

125g 4ft long octagonal


10g hospital
-empty- :]

Start out weekly, during the partial water change; if the sponge is dirty, then do it weekly. In my 10g and 29g tanks I do it weekly, as it collects a lot of stuff. The 20g only has a small shoal of tiny fish, so I may leave that sponge for 2 or 3 weeks. I have plants in all tanks and that has a bearing. With no plants I would be much more vigilant.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
