I have a nano tank with IOS consisting of 3 compartment, first compartment with sponge which i wash regularly once a week, the second compartment consists of

1. Carbon

2. Ceramic Rings

3. bio-ball

4. another layer of sponge

Can anybody tell me when should i change these following media ? ceramic rings, bio-ball, carbon etc, once a year, interval of 3 months ?

If you asking the frequency of change, the just replace the carbon and sponge half-yearly. The rest can waste and reuse every 1 month, for me.

what about ceramic rings ?

change half-yearly too ?

the surface of ceramic ring do wear out after a while . get biohome. i dun really replaced that.

thanks... The bio-ball should leave it right ?

[Marinesavy]

hammy, thanks.... heard that biohome also digest nitrate... should be wonderful if is able to do that since water change from tap water also contain certain level of nitrate.

Can i actually use combination of bot the ceramic rings and biohome. Carbon will be replace half yearly and the bioball should be left untouch.

i think carbon shld be replaced about 2-4weeks per usage as it may release back watever is being absorbed back into the system..
