Is chaeto capable of growing with activated carbon bag also in the sump?

GAC will have no big impact on macroalgae, except that it may export iron faster (by binding organics that bind to iron) and you may want to consider dosing some iron. 
Didn't know about the Iron, thanks Randy.
In addition, Chaeto will need Phosphate to grow, so a more interesting question might be: is chaeto capable of growing while carbon dosing to manage N, P?
I'm not sure about the answer to that but would be interested to hear from folks using both. The reason for having chaeto with carbon dosing would be purely as a "home" for pods and maybe a reverse photoperiod to help limit Ph swings rather than nutrient export.
I'd like to setup a fuge to grow pods, but still not gotten around to it yet. Not sure if the type of macro makes much difference if the purpose is a home for pods rather than export. Anyone?

Depending on how much organic carbon you dose, you may drive N and P low enough that the macroalgae will stop growing or even die. But you need not drive it that low unless you want to.
I did not find that to ever happen in my system using Caulerpa racemosa, but Chaeto needs more nutrients in the water, apparently.

Couldn’t agree more with randy, I use the most morphic form of racemosa called laetevirens, our local morph to be precise and it and chaeto together were surprisingly different when using activated carbon and I tried a lot of other issues out on both.
From what our specialist algae folk that advise the government on algae issues told me and tried it out as well, chaeto has a greater amount of symbiotic cyano on board compared to any form of caulerpa including racemosa! All plant life in and out of the ocean has with in and relies on its symbiotic cyano, in fact they like to refer to cheato as being very closely related to blue green algae.
Though chaeto is a single cell alga, as in the whole section that is intact is classed as one cell just like caulerpa, its chloroplasts content of cyano is different and the cell outer wall structure that allows penetration of surrounding waters to enable nutrients in, is quite different as well making chaeto far better at nitrate removal and no where near as good at removing phos and general toxins and pollutants as good as racemosa can carry out.
I found algae needs the same, “more or less”, dosing as sps and I use human grade swiss liquid iron from the supermarket and it works a treat. You see when it imports and you export as in trim and throw away, you are trowing away mag, amino, iodine and much more that has become the algae’s make up, you have to put all of it back via dosing.
I do dose, but I boil my trimmed algae and put it back in to be absorbed and used and broken down by the nitrogen cycle. Of course my system is so large it is impossible for nitrate to be present.
Most of what the algae takes up is converted via photosynthesis and nitrogen fixing to harmless and useful substances for symbiotic life’s algae and algae on its own, so I put it back in so all can use these substances.
That’s part of my natural way of carbon dosing, along with some shoreline algae at low tide I get and I boil and ad its fluid I dose with as well from time to time.
