I have a FOWLR system with ugly diatoms, and I used some silica sand... so the diatoms aren't going away.
Kalk is supposed to help remedy this, but I'm supposed to drip.
I want to drip without buying yet *more* equipment (especially since this is a FOWLR).
I have extra baby bottles. I was thinking these could drip nicely.
What do you think / recommend?
