Best bet would be to buy an additional diatom filter and retain the eheim
for mechanical/biological filtration.

Hello all,

I know that Eheim does not make one, but is it possible to buy a diatom
bag
w/ powder from another brand and place it in the 2213 canister filter?
Ever
since I added some top up sand (that has been sitting in my rinsing bucket
outside for a few weeks) to my tank, the water has been cloudy, no matter
the water changes, and seems to get progressively worst.

Cheers,
