Quetsions Regarding Eheim Filter and Susbtrat Pro Replacement

[nagukush]

Hi Friends !

Hope all is well !

I have 2 doubts regarding assembling the Eheim Filter and Regarding the Eheim Bio Media - Substrat Pro and wanted to request you all to kindly guide me regarding the same...

I just found this article regarding cleaning and assembling the Eheim 2217 and according to it -

"You first want to cut about three inches off of each size of tubing. These are the pieces that you’ll connect to stem on the top of the filter and the stem protruding from the lower side"

Kindly advice if 3" of length is enough for connecting the Tubes to the Filter Openings - I always keep about 8 to 10" - Kindly advice which will be better. It will be very convenient if 3" is enough but I'm afraid that it might be too short and might come off if pulled a little. Kindly guide me.

Also according to the Article, the Eheim Biomedia, Substrat Pro needs to be replaced at every cleaning (3 months), but I thought that the Biomedia could be used forever - if it needs to be replaced then it will be not practical at all, as its so expensive here in India.

Kindly guide me regarding the above friends...
Thanks and Regards
Kush

There is no need to replace substrate pro unless they have been grounded into power form over time. (I know of people still using the same batch of substrate pro after 10 years)

Just watch your substrate pro in aquarium water as per recommended and you will be fine.
