Well the video looks better on my phone (ugh compression). I see what you mean regarding the hydrozoans.Little hard to see but I feel like I can make out hydrozoans. I have a bunch in my tank that are similar to the photo below. I used to be concerned but they come and go..don’t bother much. More of an eye sore. Some varieties can do some serious damage with a nasty sting. maybe if you can get a good still photo? The ones I have will get all sorts of stuff trapped in their “structure” giving it a fluffy appearance.
I really can’t be sure though I can’t see that well. The other thought I had was maybe some sort of biofilm created by a bacteria, but I thought I could see little polyp heads on some.
Looks like pods of some variety (I see multiple kinds) - I can't tell what specific kinds they are from the video, but they're most likely harmless/beneficial for the tank.However what I’m more referring too are the little creatures that appear inside the fluffy stuff and move around. I’ll try to get a picture of them after work.
I am carbon dosing (very slowly). Started about 10 days ago. Maybe that's part of it.Honestly to me that kinda looks like blooming bacterial film with pods crawling on/through it
What can cause a bacterial bloom ? What’s the typical ?Bacterial blooms typically either go away with time, or when the problem that caused the bloom is fixed.
High localized nutrients. If its like ops. If its in the water column high nutrients in the water.What can cause a bacterial bloom ? What’s the typical ?
High nutrients, a clump of something decaying that there aren't enough scavengers to clean up quickly, or occasionally something like a temperature or parameter swing unbalancing the tank and giving the bacteria a chance to multiply. Or, occasionally, new tanks just get them as part of the stability working itself out.What can cause a bacterial bloom ? What’s the typical ?
