Should I Buy an External Filter?

[Guyb93]

My filter cleaning is a wonder weather I’m doing it right I’m cleaning one of the two trays each month just rinsing in treated water then back in , my internal gets cleaned when ever it looks nasty to be honest , I’m thinking I could clean my filter more but it’s not all tht big to hold the bb needed for my footprint , it’s a fluval fx4 by the way

I have 2 smaller internals in my 180 litre (yes, there is a reason why I have 2 small instead of 1 large) and I clean them alternately, one every week so they each get cleaned every 2 weeks.


[I had one filter in the tank, then the pump died. Luckily in the cupboard was a smaller filter from a tank I'd closed down, of the same type. The pump part is exactly the same size on the filter range, just more powerful as they get bigger. So I used the pump from the smaller tank, and instead of buying a new large filter I bought a second smaller - and cheaper - one and split the media between the two filters]
