algea id

Could someone I D this algea for me, been battling for over year. Seems to grow only on back and 1 side of tank. It's a reddish brown, turf type, covers coraline and kills it, cleanup crew/ fish won't touch it. Been trying to combat it with different types of bacteria but with little success...

Thought I was having an algea bloom....but have chaeto in sump. Nitrates are 2.0- 2.5 and phosphates are .08 - .04 consistently. Wondering it this is actually Diatoms, and if so, best way to exterminate. I have been running U.V. for 2 days. Very minimal change. Help!?

Hello everyone If anyone would be kind to help us in our new tank. We have had it for 2 months now and just last week this showed up. We can't get our hand on what it is exactly. We have caribsea Life Rock and life sand Ammonia - 0 Nitrite - 0 Nitrate - 20ppm Lights are on for 6 hours We do...

Hey guys, So i have a 40B Parameters are ALK: 12.5 CALCIUM: 430 MAG: 1230 NITRATE: 11.3 PH: 8 PHOSPHATE: 0.33 I did just change from Cora life to red sea coral pro salt. And the only new addition to the tank is chaeto. I did have a coral that died but i took it out of the tank once it went...

Hello, first time poster, and unfortunately it's to identify a strange looking algea. It doesn't really look like algea, I suppose it could be some sort of hitchhiker, but I haven't really been able to find anything quite like it. It's mostly translucent, but has "tips" almost like a coral...

So, recently I went out of town and the AC went out. my tank temp when I got back was really high (90C), and I very quickly got it back down to 76 where I keep it. my clownish survived but by the time I got home, my corals, shrimp, and snails had all died. shortly after this weird fuzz showed up...

Help!!!!! So all my livestock has been in this tank for a couple months. I think everything has been in here since March 29th 2021. The 2 Cerith snails I believe i got a little later Maybe early June. So introducing stuff only could have happened awhile which leads me to my first observation. I...

Hi, my sump, my skimmer, filter socks and even chaeto is covered with what seems like some film aglea, (diatom, cyano?) It's rust colors. Been like that for 2 weeks and it's only in the sump, DT is clean. Any help is welcome. Thanks!

If I need more quality pics let me know. I’m new to the game so can someone id this for me with what I’ve got? Can iPhones not upload videos to this site?

ok so back in december when i started my tank i got this rock and this rock has been chipped broken and everything but one thing stays the same its always been covered in caroline algae and then the i have absolutely no idea algae or bacteria i’ve tried everything like scraping the rock fully...

I’ve got this algea that isn’t red slime and isn’t coralline I don’t think. It may be some different kind of coralline I’ve never seen. It’s not encrusting it’s more like it just covers areas of rock but it never gets slimy or hairy. I have red and I just discovered orange.

I have regular purple coralline growing on my rocks. I also have this very light blue colored algea that looks similar and a hard green algea on some of my other rocks. Are these coralline? Also some white colored areas on my back wall. Is that the start of coralline?
