Chaeto reactor not doing so well.

I have had this chaeto reactor running for 2 weeks now on a month cycled tank and have had noticeable growth - maybe doubled in volume from the baseball size it was.

But now I am seeing some brown growth on top of the chaeto which was once bright green (see below) and on the acrylic. Some of the chaeto is even becoming pale, just look closely at the photos.

I am guessing this is some cyano or diatom that is covering the chaeto and blocking light and/or respiration .

I have very high nutrient levels and I run the lights 24/7. Running the lights 24/7 should not be a problem as I have seen many do this with macro reactors with no issues and great growth. It seems to just be stunted by this brown growth. Or maybe that is not what haa stunted it, I do not know.

Any tips?

Is the brown just a natural step? Should I wait it out? Has yours been on reverse cycle since day one?

That looks great Scuzy. What kind of led string are you using if you don't mind?

Scuzy -

Was it a relatively new tank when you had the brown outbreak? I think it might be a diatom outbreak i am having.

I asked the same question a few weeks back. It's like it cleared and the whole reactor walls no longer had stuff stick to it.

Maybe 24/7 lighting only works in low nutrients which discourage mircro growth on the macro algae. I have very high nitrates atm.

Maybe the chaeto lowered nutrients enough to not encourage that kind of brown growth?

Im all but certain it is just something you have to deal with when you have high nutrients. I washed the chaeto off today and it was bright green underneath.

What are the benefits of running a reverse cycle?

I don't turn lights on in my tank except to view the tank because it is a peacock mantis tank. They don't like light.

I think that kind of reactor may work for 5 Gal. tank, if you really want to see drop on PO4 and Nitrate have to be a "way" much bigger.
i use 90 Gal. tank (refuge) for 300 Gal. tank, yes i do NOT use GFO anymore.
