If I only had a sponge filter with skimmer, would I still be able to dose vodka and still get the benefits from it?

No substrate or rocks?

One concern may be limitations to the surface area for bacteria to attach, and some possible concern that bacterial growth from the vodka might actually take up the available surface area so that bacteria driving the nitrogen cycle are limited in numbers.

Randy I forgot to tell you that the system has a wet/dry with no LR and LS.
Thanks

So I do not know if my hypothesis above is valid, but it would concern me even with a wet dry.
