Are these Dino’s?

I thought this was Cyano has been there for a little over a month. And never had bubbles but today it does it has a reddish tint.

if your talking about the red stuff it looks like Cyano. Only positive way to tell Dino’s for other stuff is with a microscope.

Both can outcompete the good guy stuff if nutrients either zero or high, or at least, we see more of this when waters unstable.

What’s levels run at normally?

If your into chemical removals (after nutrients stable) then you can eliminate cyano rather easy with a chemi clean treatment.

If anything remains, assume Dino’s, which is a longer process of removing manually daily, small hits of phyto every few days and if they can move into the water and off the sand, then UV works great when lights out.

Simply a numbers game cause Dino’s multiply fast.
Keep reducing their numbers and feed the system good guys, you’ll reach a point whereas those good guys , outcompete the bad and sand and rock stays clean.

Takes a bit of time (8 weeks for me) but they just disappeared on their own and have not returned.

based on that picture, you have color mixes of red, brown and tan/green.
This is going to be a mix of things including cyano.
