fillteration help

[poolgirl]

Hello can some one please help me. I recently upgraded my tank from a 52 litter tank with a built in spong fillter to a 230 litter tank with what i think is a gutter filter. Could some please tell me how often i should change the filter wool.

Well! Welcome to the forums

It would really help if you can tell us specifically what kind of filter it is, make and model. If not, is it internal/external etc

The filter media shouldn't be changed very often at all if it is a biological filter, as the bacteria live on the media, and a complete loss of bacteria (as you would get in a change of media) would suddenly see ammonia and nitrite levels rising.
Which is bad

Do you know of cycling? Ammonia->Nitrite->Nitrate?

Sorry it took me so long to get back to you i got a bit lost in the site.
The tank has a pump in side the tank which pumps walter up in to the hod the unit has 3 compartment in it. The first one has what looks like carcoal coved whit a thin layer of foam. The second has small white tubes in it coved with the filter wool.
The third just has the filter wool in ti and the last is where the water falls back in to the tank. I have been keeping fish for about 2 years now and i do cheak the nitrates, nitrites, ammonia and ph on a regular basis

Id say it sounds like a HOB filter... Could be wrong...

Is that a Boyu tank, maybe the HX-1000. I have the HX-800. The filter wool that it came with clogged up very quickly, so I slowly changed the filter and now has a 3 stage foam filter with a biological (ceramic tues) filter. It works alot better now and the tank is very stable (except for my dieing fish!). It doesn't need cleaning (large debris rinsed off in old tank water) as often now.
