Acorral's UAS test

[acorral]

This is second cleaning after changing to 8on and 8 off








Based on the color of the algae I'm thinking about moving to 9 on/ 7 off and see what I get... any opinion from the experts here will be appreciated !!!

Looks great.

[acorral]

Looks great.

Thank you !!! what do you think about adding one ON hour and reducing one OFF hour ???

[acorral]

As I move forward eliminating the bryopsis algae on my display tank, I'm getting some black cyano mat on my sand bed... is this normal behavior when getting rid of the algae or something isn't right?

Great news!

[acorral]

Great news!

Yes Srusso, thanks to the UAs and you personal advice I'm getting rid of the Bryopsis... what do you think about the Cyano ??? is that part of the process of getting rid of the algae ???

[SantaMonica]

You could add hours, since the growth is not bright green.

Point a powerhead near the sand to clear the cyano.

Good news !!!

Bryopsis is 90% death !!!! I guess the die-off from the bryopsis was fueling some cyano or dinos on the sand (not sure if it was cyano or dinos or both)

I have been sweeping the sand lightly with a powerhead once a day

Added some fresh activated carbon

Renewed my UV bulb and lowered the flow on it to make it more effective on rising ORP

And today I finally saw white sand witout any cyano or dinos, just with some light debris on it that I siphoned out !!!

I expect to have finally defeated the bryopsis algae at 100% in something around 2 weeks

After that I plan on keeping the same feeding and scrubing regime fro 3 months to make sure Bryopsis is gone and then I will start rising the feeding again to my corals and fish, at that point I may also consider changing from UAS to ATS to take advantage of the extra oxigenation on the ATS and be able to shut down my skimmer... not sure right now but I may go skimmerless in some time !!

Acorral hermano de verdad es una buena noticia lo que colocas, dios quiera que ya en 3 semanas veamos ese acuario sin bryopsis

Lo de la ciano estoy seguro que son los desechos que deja la bryopsis que nadie más efectivo que la ciano, pero como bien dices era algo pasajero

Ahora recuerda que la oxigenación que se comenta por el ats no es tanto por el movimiento si no por la misma alga que inyecta oxigeno directamente en la columna de agua, así que uas o ats creo sería lo mismo con respecto al oxigeno; aunque puede afectar el crecimiento, como te comente antes, al uas lo que todavía no veo es un buen crecimiento de alga, aunque esto pueda que no tenga que ver con consumo de nutrientes, no lo sé, abría que experimentar

Saludos y un gusto saber que vas ganado la batalla

My Spanish is almost non-existent. I dont know what you are trying to say about the oxygen and growth. This should not really effect the Bryopsis or the cyano.
bryopsis is hard to beat even with a scrubber!!! Its tough for sure.
Congrats on your battle. I still have a little tuft of it pop every now and then.
