    Hi,
    I'm about st my wits end. I cannot get rid of this algae. I'm assuming it's Cyano but not 100% sure. It comes off sand bed in a "sheet" if I'm careful when I remove it. I have siphoned the sand multiple times, water changes, lights out for 72 hours. It always comes back. Is there a way to know if it's definitely Cyano? It seems too dark for diatoms.

    Unfortunately, I'm having some health issues and cannot stand for very long. So I'll have to have a friend help with whatever suggestions y'all have.

    Thank you.

    Think it looks more like dinos, and not cyano...

    I agree that it doesn't look like Cyano.

    This is an easy way to check if it is.

    Please consider sending a sample out for ID. I can not say for sure what it is but it is 1 of 3 things. Need a scope shot.

    Hey I was curious about the rock your using since ur in Texas also. It kind of looks like the natural limestone we have here in San Antonio, I use a few pieces along with real LR in my tanks from time to time but I also do get some bacterial blooms from time to time but haven't correlated the two things for sure yet.

    Doesn't really look like dinos to me.....looks more like a mix of cyano and diatoms? Dinos, in my experience (unfortunately) have much longer strings with bubbles. Dinos also don't really come off in mats. Have you checked your nutrients (nitrates, phosphates)?

    Does not really look like Dino to me either. If you're at your wits end try Chemiclean, use as directed per product instructions, add supplementary O2 source during treatment, do a water change 48 hours later.
    As posted check your nitrate and phos levels.
    These algae issue can extremely frustrating. There are interventions it's just a matter of what works for your tank.
    Correct any water quality issues, modify feeding regime, modify lighting and filtration, add phos reduction products, but do one intervention at a time and allow time to adequately see results.
