Hi Friends,

I have this Tank-Top Filter on my 4 Feet Frontosa tank and just wanted to request you Friends, to kindly guide me on what filter media should be the best considering my current situation.I'm attaching a few pics for you to have an idea what the filter exactly looks like (mine infact is the same one) and its scope of media.

My Current Filtration on this tank

2 x Eheim 2217s - with Eheim Substrat Pro and Other Eheim Mechanical Media
2 x Eheim Internal Filters - with the normal filter media that comes with them

Now, I've configured this Top Filter in such a way that on of my Eheim 2217's output feeds the Spray bar of the Top Filter.

I totally have 3 Filter Media Baskets in this Top Filter and I've planned to use it as follows -

Basket 1- Activated Carbon ( Will be Replaced Monthly or once in 2 months)
Basket 2 - Crushed Shells and Coral Pieces to raise & buffer the pH and Hardness
BAsket 3 - I'm not sure what to put in (Ceramic Rings / Cylinders ?), but I plan to put Eheim Substrat Pro when I can afford it.

Will be a great help if you can kindly suggest me a good media for the Basket 3 and please advice if my above stated plans are ok.

Kindly guide and help me Friends - Thanks a lot !
Lots of Regards and Care to everyone !
