Algae ID help - GHA, Byropsis or something else?

[r0cksteady]

Hi All,

Could I please trouble you to cast your eye over these and assist with a positive ID. Ive been treating the tank as if its GHA but having no luck ie. clean up crew, rabbit fish etc not eating it so just want to confirm its not something else.

Regular GHA...

Have you tested for phosphates/nitrates?

Thank-you for your response. I thought it was GHA but after getting the nitrates down to zero and the phosphate down to 0.04 for a solid month I thought it would die off. Its certainly not growing anymore but its also not reducing.

The calerpa in the reefugium is also stagnant so im at a loss as to waht to do next. Ive added twinbar, foxface and scribbled rabbitfish, bristletooth tang, abalone and snails but they arent really eating it.

Is it easy to remove by hand?

I'd pull out a rock or 2 each day and do a 50% old tank water/50% hydrogen peroxide soak..
Leave the rock in the solution for roughly 15 minutes as you scrub with a toothbrush..
Rinse it off then put the rock right back..

And keep working on keeping those nitrates/phosphates low..
