bacterial brown slime how did you beat it?

Devaji · Dec 22, 2023

so I have a newish tank now 4 months old did a long slow dark cycle of a bout 6 weeks. turned on the lights 2X AI blades. added some photosynthetic gords. a few weeks later some macros. one melded then a few days later I got the brown slime bac, stuff going on.

it easily comes off when i do a WC. I take a tooth brush as brush it off the rock. take looks great for 2 days then comes right back..

tank info:
RS 300Xl
will be a seahore tank
only animals are a few snails
macors and gorgs

flirtation:
reef mat the I am not using yet
BRS mini reactor for carbon and GFO not using yet
skimmer
25W UV ran after 6 week cycle

I used dry rock and dry sand.

I am thinking lights out for a few days would do wonders for this stuff, however i have 6 photosynthetic gorgs that are doing quite nicely i dont want to kill them.

been like this for 2 months now was seeing if nature would sort this out on it own. + I was out of the country for 3 weeks in NOV so i just let it do its thing. but I feel now it's time for some human intervention.

my thoughts are:
add pods after the new year ( shipping is nuts this time of year)
a few days with lights off.
look into CUC that eats the stuff that is also seahose same.

i'll post a video so you guys can see the ugliness.

so how did you beat the stuff?

TLDR:
brown slime algae taken over take for 2 months. yes I have UV.
how long can gorgs survive in black out?

thanks I think you are 100% right there.
sadly I dont have a micro scope around to verify it.

so reading around it seems ( older threads) that vibrant could work. as i dont have any LPS or SPS this could work but on the other hand it could kill my macros? not sure there.

some say a black out helped but not solved it. maybe it could weaken it so the algaecide could beat it back?
replace your DI

cant add a fox face as this will be a seahose tank so 95% sure just gonna be a species only tank might add a fire fish or mandarin down the rd. but focusing on the SH.

@ScottB am i right here thinking that eother vibrant or alagefix is my best next steep?

I tossed my vibrant after all the Info came out that is was not a bac. product but an alagecide. it did work on a little nano i had tho. but left a bad taste in my mouth. maybe API alage fix is the "better" product here?

anyone else have info on how they beat Chrysophytes?
