Habitat - Indoor :: When to replace Reptofilter cartridge?

[easy2putt]

I'm using a Tetra ReptioFilter with the replaceable cartridge. When should I replace the cartridge? What are some signs? Water seems very clear still. It's been about 7 weeks.

Depends on the bio-load of your tank, I'd think. Also, depends on what cartridges
are installed. For mechanical filtration media, you can clean it about monthly or
bi-weekly with heavier bio-load. For activated carbon, you need to replace it
probably bi-monthly. For biomedia, you can rinse in tank water maybe bi-monthly
and replace after one year if not longer.

Perhaps others have different opinion

I had a tetra repofilter and (although I hated it) it was my first filter.
It doesn't do much if you have a tank bigger than 10g.

but, to answer your question, you could just open the lid of the filter and check the filter pad after a couple weeks, and depending on whether the filter is grimy and poopy, you can determine whether you need to change it

or if you see that there is a lot of poop laying at the bottom of the tank, then the filter pad is no longer catching it because it is full. If anything, just check.

If I replace the cartridge will the water in the tank get cloudy again? It is crystal clear right now..but I do see floaters and probably poop stuff.

I want to replace the cartridge and remove about 50% of the river rock as well. I like when they dig through the river rock..at least something they can do..so I don't want to take out oo much.
