Bacteria, do you carbon dose?

Yes, I used to. I stopped dosing 3weeks ago.

I would say it is just harmless bacteria. When I was heavily dosing vinegar, I had a lot of pink snot in high flow areas.
Cheers! Mark

Thank you for your reply. Sounds nice!
Will it disappear someday?
Its annoying. clog filter, Trident, etc...

It comes with the territory. Higher flow will get it moving along. You can try adding something like seachem pristine or dr. Tim’s waste away. They’re additional bacteria that break down detritus and what not. I’ve used pristine before and noticed my mechanical filtration was taking longer to get gunked up.

You could try to siphon it all out with a water change. If your not dosing carbon, it shouldnt come back I would think?

I siphoned almost all of them. But it seems still growing.
I wondering if I should add some chemicals or wait.

I'd rather not use chemicals if it will be eliminated in course of time.

You could try to add a competing bacteria like ZeoBak or one of the other brands? Better than having GHA in my book.

Im dosing soil bacteria sometimes. Seems like its not working.

Well I would guess that may be what your slime is?
