Hi Jerry,I will look at the photo on my computer later. Are you sure it isn't cyano?
A lot has changed from when I first noticed it. I would say it started after the cyano battle which lead me to remove the DSB around 4 year ago. lights did change to LEDs but i feel it started before that. Its been a while since i tested NO3, let me pull out the test kit.Started a 'few years ago'......what's changed a few years ago? Certainly no diatom guru, but hate seeing a long time reefer getting to his wits end. We do love our 'detective stories' on occasion, so I sure hope we can get to the bottom of this for you.
Yes, the 'powdery' description makes it sound like diatoms as opposed to a 'film algae'. I don't know if the 'web' is getting confused, but it had always been a fresh source of silicates was the cause......and when depleated, the diatoms died off.....new rocks, new sand BOOM! BUT they die off. But a quick search on the web tonight is also now throwing 'too much lighting', and NO3 into the mix as well.....NEVER HEARD OF THAT! THAT sounds more like they're getting things mixed up with 'brown algae'.
You seem to be doing everything right....0 TDS, brute trash cans....most often suggested.
Just for giggles, did you get new lighting about the time this started? And just for another giggle.....what is your NO3 readings like recently?
Pulling for Ya,
I am starting to think it DINOs too. it would seem everything I been doing (trying to be crazy clean) is feeding them. I have been getting so frustrated that right after a water change they would come back hard. I was thinking i had high silicates and or phosphate in my source water. Now I am thinking i have been too clean...I looked at the first photo as large as I can get it.
Are the bubbles attached to the red substance, it appears so?
the stuff on the top of the rock on the right hand side does look like DINO
kind of stringy with bubbles.
Might try bumping up the phosphates a hair.
incorrect, the photo is a little miss leading, the bubbles in that photo are on the glass and not in stringy appendages of red stuff.What I am basing the thoughts of Dino on is the first photo you posted.
In the upper right hand corner of the photo the rock comes from the side of the photo and curves up.
After a bit it makes a sharper climb toward the top of the photo. Just to the right of where the rock sharply curves up there appears to be bubbles attached to stringy appendages of the red stuff. Is this correct?
