Filter media for a terapin/turtle tank?
I have a large exterior canister filter, which is of course sold to be used with fish.
I wondered if I could use different media to better effect seeing as;
I clean the filter out and do full water change every week,
don’t really have time or space be able to wash filter media in same temperature water(killing the good bacteria, so I understand)
turtle poo from older turtles doesn’t seem to break down so easily (think its that plants and prawns in their diet)
At the mo’ I have:
50% sponge
40% ceramic doughnut things
10% carbon
Is there any point to the doughnuts if most of the waste removal seams to be physical rather than biological?
What benefit does the carbon have, how often should I change it (don’t like to ,its expensive!)?
Should I get more sponge?
Would a fluval ‘polish’ sponge prevent of the discolouration of water that sometimes occours at the end of each week, have you ever used one?
Do you think I should work harder to cultivate the bacteria?
