I made a mistake several days back and did too much cleaning. I cleaned my canister filter and the hoses (which were disgusting) and must have removed too much bacteria. Fast forward to today and my water is green.
I got a UV filter to help, but wondering if it won’t do more damage to the bacterial population. I’ve been adding cycling bacteria to try to help get my tank back to normal, but wondering if I’m not essentially going to end up destroying more of my nitrifying bacteria!

Any advice on how to best manage the chemistry through this mess?

You can just use the sterilizer, the damage to the beneficial bacteria populations is miniscule. Be sure to check ammonia a few times and it wouldn't be a terrible idea to increase surface agitation to prevent any issues with oxygen in the tank.

Thank you!!
 
The water might be too green to see clearly, but I see no powerheads and no rocks?

Do you dose phyto? Do you run carbon?

have you done any water changes?
 
A UV is not going to do more damage to the bacterial filter.
Consider adding an alternative O2 source until the issue resolves. If you have a skimmer that would work to facilitate gas exchange too.

It’s just too green to see. Plenty of rocks and two powerheads. No, I don’t dose phyto. I’ve been using the carbon pads, not granules.

I added a pic of the tank when it’s normal (from months ago).

The UV has cleared it up a lot already!

Thank you! I have a small skimmer on it.
